Question

Find the breadth of the rectangle if its perimeter is 100cm
and its length is 20 cm.

Answer 1

Answer:

breadth is 15

Step-by-step explanation:

Answer : Length = 35 cm and

Breadth = 15 cm

Given that : The perimeter of rectangle = 100cm

And also given that : the length is 20 cm more than its breadth.

Let, the breadth of the rectangle = x cm

Then, length = (x+20) cm

As we know that :

The perimeter of rectangle :2[l+b]

2x+20=50

2x=30

x=15

the Breadth = 15 cm

and Length = x+20 = 15+20 = 35 cm
