Question

The perimeter of a parallelogram is 80 m. If the longer side is 10 m greater than the shorter side, then find the length of each side

Answer 1

Given :-

The perimeter of a parallelogram is 80 m. If the longer side is 10 m greater than the shorter side

To Find :-

Length of each side

Solution :-

Let the smaller side be x

Larger side will be x + 10

2(x + x + 10) = 80

x + x + 10 = 80/2

2x + 10 = 40

2x = 40 - 10

2x = 30

x = 30/2

x = 15

Therefore

Smaller side = x = 15 m

Larger side = x + 10 = 15 + 10 = 25 m
