Question

The perimeter of a parallelogram is 150cm the shorter side is 15cm less than the longer side find both sides of the parallelogram

Answer 1

Answer:

30cm, 45cm

Explanation:

Let one side be x and other side be x+15

P of parallelogram = 2(l+b) = 150

2 (x+15+x) = 150

2 (2x+15) = 150

4x + 30 = 150

4x = 150-30 = 120

x = 120/4 = 30cm

x+15 = 30+15 = 45cm
