Question

the perimeter of a paralogram is 140cm .if one of the side is longer the other side by 20. find length of each side.​

Answer 1

Step-by-step explanation:

let The One side be x

then The other side = x+20

Perimeter of parallelogram = 140 cm

according to given condition,

So, perimeter of parallelogram = Sum of all sides

or, 140 = x+(x+20)

or, 140 = 2x + 20

or, 2x = 140 - 20

or, 2x = 120

or, x = 120/2

or, x = 60

therefore One Side Is 60cm

And other side =(60+20)cm = 80cm
