If the perimeter of a rectangle is 32 cm and its length is 9 cm, then the breadth of the rectangle is

Correct option is D

Given:

Perimeter of a rectangle = 32 cm

Length = 9 cm

Formula Used:

Perimeter of rectangle = 2(Length + Breadth)

Solution:

Now from the formula; 

32 = 2(9 + b)

16 = 9 + b

b = 16 - 9 = 7 cm

Thus, Breadth of the rectangle = 7 cm
