Question

(14) The perimeter of a parallelogram is 150
cm. Find the lengths of its sides if one
of them exceeds the other by 20 cm.​

Answer 1

Answer:

27.5

Step-by-step explanation:

2(x+x+20)=150

x=27.5

Answer 2

Step-by-step explanation:

Let one of the sides of parallelogram be x cm

then adjacent side will be x+20

Perimeter of parallelogram =2* sum of adjacent sides=2(x+x+20)=4x+40

Thus 4x+40=150

4x=110

x=110/4=27.5

So one side is 27.5cm and another is 47.5 cm
