Question

The area of a rectangle is 117 square meters. The width is 9 meters. What is the length of the rectangle?

Answer 1

Given,

Area of rectangle = 117 m²

Breadth (width) b = 9 m

We know that,

Area of rectangle = l * b

117 = l * 9

l = 117 / 9

l = 13 m

Length = 13 m Ans.

Answer 2

Concept:

If the length of a rectangle is L and width is W then the area (A) of teh rectangle is given by,

A = L*W

Given:

Given that, the area of a rectangle is 117 square meters. The width is 9 meters.

Find:

The length of the rectangle.

Solution:

Let the length of the rectangle be = L meters

Given that the width of the rectangle is 9 meters

So the area = 9L square meters

By the problem this area is 117 square meters

The required mathematical equation is given by,

9L = 117

L = 117/9, On dividing 9 from both sides

L = 13

Hence the length of the rectangle is 13 meters.
