Question

The length of a rectangle is six -fifth of its breadth. what will be it's area if it's perimeter is 132 m​

Answer 1

Step-by-step explanation:

use the formula for the perimeter of a rectangle, P = 2L + 2W to solve the problem.

Given: P = 132 m, W = x, L = 6/5(x)

Substitute into the formula gives:

132 = 2(6/5)(x) + 2x

132 = 12/5(x) + 2x

Multiply both sides by 5 to clear the fraction gives:

660 = 12x + 10x

660 = 22x

Divide both sides by 22 to find x:

x = 30, or the width is equal to 30 m.

To find the length, multiply 30 by 6/5, which gives 36.

The length of the rectangle is 36 m and the width is 30 meters.

Check: 132 = 2(36) + 2(30)

132 = 72 + 60

132 = 132, values check!
