Question

the perimeter of a parallelogram is 260 cm one of its side is smaller than the other by 20 cm​

Answer 1

Step-by-step explanation:

The perimeter of a parallelogram is 260 cm. If one of the sides is smaller than the other by 20 cm.

Let smaller side (a) =x then longer side (b)=x+20

Perimeter =2(a+b)=2(x+x-20)=260

=> x=60

Smaller side =60-20=40cm Larger side =60cm
