Question

A rectangle has an area of 99 square in. What is the length of the long side?

Answer 1

The longer length is either 99, 33 or 11 inches

Explanation:

Given

`Area = 99`

Required

The length of the longer side

Area of a rectangle is:

`Area = Length * Width`

List out all possible products that give 99 [Assume the dimension are whole numbers]

`Length * Width = 99 * 1 = 99`

`Length * Width = 33 * 3 = 99`

`Length * Width = 11 * 9 = 99`

List out the longer factors

`L = \{99, 33, 11\}`

Hence, the longer length is either 99, 33 or 11 inches
