Question

The length of a rectangle is 5meters more than its breadth lf the perimeter of the rectangle is 40 meters find the length and breadth of the rectangle

Answer 1

breath=7.5,length=12.5

Answer 2

Let breadth be x meters.
So length will be x +5 meters.
Perimeter of rectangle is 2(l +b)
2(x + x +5)=40
2(2x +5)=40
2x +5 = 20
2x =15
x =7.5
Breadth is 7.5 m
Length will be 12.5 m

Hope it helps
