Question

The perimeter of a parallelogram is 140cm. If one of the side is longer than the other by 10cm find the length of the longer side. *

Answer 1

Answer:

40

Step-by-step explanation:

Let the smaller side=x

let the longer side=x+10

perimeter=x+x+10+x+x+10. bcz opp.sides are equal of Parallelogram

4x+20=140

4x=140-20

4x=120

x=120/4

x=30

longer side=x+10

30+10

40
