Question

A rectangle has an area of 60 square meters. The width is 4 more than 1 time the length. Find the length and width, in meters of the rectangle

Answer 1

• length: 6 m
• width: 10 m

Explanation:

The product of length and width is the area, 60 m². The width is 4 more than the length, so we need factors of 60 that differ by 4.

60 = 1·60 = 2·30 = 3·20 = 4·15 = 5·12 = 6·10

The last pair of factors, 6 and 10, differ by 4.

The width is 10 meters; the length is 6 meters.
