Question

If a rectangles perimeter is 100m and the length is 40m what is the breadth

Answer 1

Answer:

10m

Step-by-step explanation:

Given,

Perimeter of rectangle = 100 m

Length of rectangle = 40 m

Breadth of rectangle = b. (say)

According to the question :-

Perimeter. =. 2( l + b )

100 =. 2(40+ b )

100. =. 80 + 2b

2b. = 100 - 80

2b. =. 20

b . =. 20/2

b =. 10 m

Hence, the breadth of the rectangle is 10m
