Question

(a) The perimeter of a rectangular field is 372 m.

If the width of the field is 87 m, what is its length?

Answer 1

The length of the field is 99 m.

Explanation:

First, multiply 87 by 2 to get 174. Then, subtract 174 (total of the two width sides) from 372 (total perimiter) to get 198. Lastly, divide 198 by 2, because 198 is the total of the 2 length sides, and you will get 99 m per length side.

Answer 2

98 m
