Question

Find the breadth of the rectangle whose perimeter is 100 m and length is 30 m

Answer 1

100 = 2(30+b)
100/2= 30+ b
b= 50-30
b=20m

Answer 2

The breadth of the rectangle is 20 m

Step-by-step explanation:

Length of rectangle = 30 m

Perimeter of rectangle = 2(l+b)

Perimeter of rectangle = 2(30+b)

We are given that perimeter is 100 m

So, $2(30+b) =100$

$30+b=\frac{100}{2}$

30+b=50

b=20

Hence the breadth of the rectangle is 20 m
