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
