Question

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

Answer 1

Answer:

Given

Perimeter of a rectangle = 100m

Length of the rectangle = 30m

We know

Perimeter of a rectangle = 2( l+b)

2( 30 + b ) = 100m

30 + b = 100÷2

30 + b = 50

b = 50 - 30

b = 20m

Breadth = 20m

Step-by-step explanation:

Hope it will help

Answer 2

Answer:

we know that Perimeter =100m

so, P=2(l+b)

100 = 2(30+b)

100/2= 30+b

50=30+b

b=50-30

b= 20
