Question

The area of a rectangle is 40 square feet. If the length is 3 times the width, then find the dimensions of the rectangle. Round off your answers to the nearest hundredth.

Answer 1

length = 10.95

width = 3.65 ft

Explanation:

Area of rectangle is length times width

let width = w

From the problem, it says that the length is 3 times the width

length = 3w

plug in to the formula

A = LxW

40ft² = 3w x w

40ft² = 3w²

divide both sides by 3

13.3333... = w²

then find the square of both sides

w = 3.65...ft

length = 3w

=3(3.65...)

length = 10.95 ft
