Answers

Answer:

Step-by-step explanation:

Parallelogram: A parallelogram is a special type of quadrilateral in which opposite sides are equal and parallel.

We have to find the perimeter of parallelogram

Perimeter of parallelogram= sum of all four sides

Let first side= 3 x+9

Second side= 4 x-5

third side= 3 x+9

fourth side side= 4 x-5(opposite sides of parallelogram are equal)

Perimeter= 3 x+9+ 4 x-5+ 3 x+9+ 4 x-5+

Perimeter= 14 x+ 8
