Question

A given rectangle has an area of 20 feet what is the length for various widths

Answer 1

The formula for finding area of a rectangle is:

`length * width`

To find the possibilities, list the factors of 20.

`20 - 1, 2, 4, 5,10,20`

`1 * 20 = 20 \\ 2 * 10 = 20 \\ 4 * 5 = 20`

Width is the smaller side. In the numbers that were multiplied ↑, the smaller numbers are the possible widths, which is also the 3 smallest factors of 20.

Possible Widths: 1 ft, 2 ft, and 4 ft
