Question

the perimeter of a parallelogram is 40cm one of its sides is greater than the other by 4cm find the lengths of all sides of the parallelogram

Answer 1

Answer:

9 cm and 13 cm

Step-by-step explanation:

The perimeter of a parallelogram is 40 cm.

If one of the sides is longer than the other by 4 cm.

Let smaller side (a) =x then longer side (b)=x+4

Perimeter =2(a+b)=2(x+x+4)=40

= 4x+4=40

= x= 36/4

= x = 9

Smaller side = 9 cm Larger side = 9+4= 13 cm
