The formula for finding area of a rectangle is:
[tex] length \times width [/tex]
To find the possibilities, list the factors of 20.
[tex] 20 - 1, 2, 4, 5,10,20 [/tex]
[tex] 1 \times 20 = 20 \\ 2 \times 10 = 20 \\ 4 \times 5 = 20 [/tex]
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
