Question

The area of a rectangle is 18 sq. cm. If its length is 6 cm, what is its perimeter?

Answer 1

Length of the rectangle = 6 cm
Area of the rectangle = 18 sq. cm
Area = Length $\times$ Breadth
Here, 6 $\times$ Breadth = 18 sq. cm
We know, 6 $times$ 3 = 18
So, breadth of the rectangle = 3 cm

Perimeter of the rectangle = 2 $\times$ 6 + 2 $\times$ 3
= 18 cm
