Question

Estimate the length of of a square floor if the area is 320 square feet.A) 16 ft^2B) 18 ft^2C) 19 ft^2

Answer 1

The area of a square is given by:

`A=l^2`

By solving for l you get:

`l=\sqrt[]{A}`

In this case A = 320 ft^2.

`\begin{gathered} l=\sqrt[]{320ft^2} \\ l=17.88ft \\ l\approx18ft \end{gathered}`

Hence, the length of one side of the square floor is approximately 18 ft
