Question

The area of a rectangle is 60 square inches. 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 (L): 3w

width (w): w

Area (A) = L x w

60 = (3w)w

60 = 3w²

20 = w²

+/- √20 = w

since width cannot be negative, disregard - √20

w = √20 = 4.47

Length (L): 3w = 3(4.47) = 13.41

Answer: width = 4.47 inches, length = 13.41 inches

Answer: width=4.16 meters, length=6.48 meters
