Question

Find the dimension of a rectangle if it’s parimeter is 100 m and it’s length is 20m more than its breadth ?

Answer 1

Step-by-step explanation:

let the breadth of the rectangle be x

given that the length is 20m more than the breadth = x+20

Perimeter=2 (length+breadth)

100 =2 (x+20+x)

100 =2 (2x+20)

100 = 4x + 40

100-40 =4x

60 =4x

60/4 =x

x=15

x+20=35

Hence the length amd breadth of the rectangle are 35 and 15 respectively.
