in such cases we always try to split the complex figure into non-overlapping simple figures, calculate their areas and add them up.
what simple figures can we see here ?
I see a rectangle 80m × 130m.
and that leaves for me a right-angled triangle in the upper right corner with the legs of
250-80 = 170 m and 130-50 = 80 m
the area of a rectangle is
length × width
the area of a right-angled triangle is
leg1 × leg2 / 2
the individual areas are
80×130 = 10,400 m²
170×80/2 = 170×40 = 6,800 m²
and that gives us a total for the whole area
10400 + 6800 = 17,200 m²

Answer:
P = 184 yards
C = 175.84 centimetres
P = 212 m
Step-by-step explanation:
P = 2(150 yards) + 2(92 yards)
P = 300 yards + 184 yards
P = 184 yards
C = 2(3.14) × (28 centimetres)
C = 6.28 × (28 centimetres)
C = 175.84 centimetres
P = 104 m + 32 m + 76 m
P = 212 m

By dividing the figure into a rectangular prism and a pyramid, we will see that the total volume is 2,400 ft^3
How to find the volume?
We can divide the given figure into two simpler ones.
A rectangular prism of 20 ft by 10 ft by 10 ft, whose volume is the product of these dimensions:
V = 20ft*10ft*10ft = 2,000 ft^3
And a pyramid of 4 sides, with a height of 6ft and a base of 20ft by 10ft, and we know that the volume of the pyramid is one-third of the product between the base and the height.
V' = (1/3)*6ft*(20ft*10ft) = 400ft^3
Then the total volume of the given figure is:
volume = V + V' = 2,000ft^3 + 400ft^3 = 2,400 ft^3

The length of a rectangle is 10 ft less than three times the width, and the area of the rectangle is 77ft^2 . Find the dimensions of the rectangle.
Answers
Answer:
The dimensions of rectangle are 11 feet and 7 feet.Step-by-step explanation:
Given, The length of a rectangle is 10 ft less than three times the width, and the area of the rectangle is 77 ft²
Let's assume width of rectangle be x feet and Length of rectangle be 3x - 10. Using the formula of area of the rectangle we'll find the dimensions of the Rectangle.
[tex] \\ \dashrightarrow{ \red{\underline{\underline{\sf{Area (rectangle) = Length \times width }}}}} \\ \\ [/tex]
Substituting the required values:
[tex]\dashrightarrow \: \: (3x-10)(x) = 77 \\ [/tex]
[tex]\dashrightarrow \: \: 3x^2 - 10x = 77 \\ [/tex]
[tex]\dashrightarrow \: \: 3x^2 -10x -77 = 0 \\ [/tex]
[tex]\dashrightarrow \: \:3x^2 + 11x -21x -77 = 0 \\ [/tex]
[tex]\dashrightarrow \: \: x(3x+11)-7(3x+11) = 0 \\ [/tex]
[tex]\dashrightarrow \: \: (x-7)(3x+11) = 0 \\ [/tex]
[tex]\dashrightarrow \: \: { \red{\underline{\underline { x = 7 \: or \: \dfrac{-11}{3}}}} } \\ \\ [/tex]
Hence,
Width of rectangle = x = 7 feetLength of rectangle = 3x -10 = 3(7) - 10 = 11 feet[tex] \therefore[/tex] The required dimensions of rectangle are 11 feet and 7 feet.
The dimensions of the given rectangle with an area of 77 ft^2 and given dimensions are; Length = 11 ft and Width = 7 ft
How to find the Area of a rectangle?
Formula for area of a rectangle is;
A = Length * Width
We are given;
Length; L = 3W - 10
Thus;
Area; A = W(3W - 10)
Thus;
W(3W - 10) = 77
3W² - 10W - 77 = 0
Using online quadratic equation calculator, we have;
W = 7
Thus;
L = (3*7) - 10
L = 11 ft

The graph of f(x) = -x2 - 2x + 8 is shown. Which of the following describes all solutions for f(x)?
O(x -x2 - 2x + 8) for all real numbers
O(-4,0), (-1,9), (0, 8), (2.0)
O(-4.0), (2,0)
O(x, y) for all real numbers
Answers
Answer:
[tex]f(x) = -x^2 - 2x + 8[/tex]
y-intercept is when x = 0:
[tex]\implies f(0) = -(0)^2 - 2(0) + 8=8[/tex]
So the y-intercept is (0, 8)
x-intercepts are when f(x) = 0:
[tex]\implies f(x)=0[/tex]
[tex]\implies -x^2 - 2x + 8=0[/tex]
[tex]\implies x^2 + 2x - 8=0[/tex]
[tex]\implies x^2 - 2x + 4x - 8=0[/tex]
[tex]\implies x(x - 2) + 4(x-2)=0[/tex]
[tex]\implies (x+4)(x - 2)=0[/tex]
Therefore:
[tex]\implies (x+4)=0 \implies x=-4[/tex]
[tex]\implies (x-2)=0 \implies x=2[/tex]
So the x-intercepts are (-4, 0) and (2, 0)
The vertex is the turning point of the parabola. The x-value of the vertex is the x-value between the 2 zeros (x-intercepts).
Therefore, the x-value of the vertex is [tex]\sf \dfrac{x_1+x_2}{2}=\dfrac{-4+2}{2}=-1[/tex]
Substituting x = -1 into the function:
[tex]\implies f(-1) = -(-1)^2 - 2(-1) + 8=9[/tex]
So the vertex is (-1, 9)
The domain is the input values, so x = all real numbers.
The range is the output values, so the range is [tex]f(x)\leq 9[/tex]
Therefore, (-4, 0), (-1, 9), (0, 8) and (2, 0) are solutions of the function, HOWEVER they are not ALL the solutions.
All solutions of the function are:
[tex](x, -x^2 - 2x + 8)[/tex] for all real numbers of x

Area = 12 + 6.25π ft², Perimeter = 6 + 5π ft
Step-by-step explanation:
Area:
So I would break this shape into a triangle and a circle (the two semi-circles make a full circle).
Formula for Area of a Triangle: base · height ÷ 2
6 · 4 ÷ 2 = 24 ÷ 2 = 12
Formula for area of a circle: π · radius²
π · (5/2)² = 6.25π
Area of entire shape: Triangle + Circle
Area = 12 + 6.25π ft²
Perimeter:
So the perimeter is made up of the base of the triangle plus the circumference of the circle.
Base of Triangle: 6
Formula for circumference: 2rπ
5 · π = 5π
Perimeter = 12 + 5π ft

Number of Handshakes If eight people greet each other at a meeting by shaking hands with one another, how many handshakes take place?
Answers
The number of handshake that took place is 28.
In any situation where order of an outcome does not matter, mathematical combination (C) are use calculate the total outcomes of an event.
8 people are to shake each other once. The concept to be use to derive the number of hands that took place is Combination.
The formulae of Combination for this Scenario is n(n-1)/2n(n−1)/2 .
The number of people (n) is 8.
\begin{gathered}Total handshake = n(n-1)/2\\Total handshake = 8 * (8-1)/2\\Total handshake = 8 * 7/2\\Total handshake = 56/2\\Total handshake = 28\end{gathered}Totalhandshake=n(n−1)/2Totalhandshake=8∗(8−1)/2Totalhandshake=8∗7/2Totalhandshake=56/2Totalhandshake=28
