Answer 1

Answer:

Other side= 30 cm, One side= 40 cm

Step-by-step explanation:

Let the other side be x.

One side= x+10

Perimeter=140 cm.

A/Q,

2{(x+10)+x}=140

=>2x+20+2x=140

=>4x+20=140

=>4x=140-20

=>4x=120

=>x=120/4

=>x=30

Other side= 30 cm.

Other side= 30 cm.One side= (30+10)cm

Other side= 30 cm.One side= (30+10)cm =40 cm
