Question

The perimeter of a parallelogram is 50 ft and its length is 10 ft. What is the length of the other side?

Answer 1

`15ft`

Explanation:

Since the opposite sides of a parallelogram are equal, and the perimeter is the sum of the distances right around the exterior of the closed quadrilateral, we may write an equation for the unknown side `x` and solve it as follows :

`P=(2xx10)+2x=50`

`therefore x=(50-20)/2=15ft`.
