Question

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

Answer 1

Let w = the width

Let 4w = the length

A = lw

96 = w(4w)

4w² = 96

w² = 24

w = 4.90 inches

4w = 4(4.90)

length = 19.60 inches
