Question

Michael is planning to build a path that is 3 feet wide and has an area of 726 square feet. Finish the array sketch below he has started to find the length of the path. I need to finish the 4 array boxes

Answer 1

First, notice that the two already labelled boxes have an area of 300 square feet each. Then, they account for a total of 600 square feet. Substract 600 from 726 to see how much additional area is needed:

`726-600=126`

Since the path is 3 feet wide, and the area of a rectangle equals length times width, then divide the area of 126 squared feet by 3 feet to find the remaining length needed:

`(126)/(3)=42`

Therefore, the length of the path needed to complete the sketch is:

`42\text{ feet}`
