Question

Elias completely covered a square canvas using 77.8 in.² of fabric without any overlap. Which measurement is closest to the side length of this canvas in inches? A. 8 in. B.9 in. C. 19 in. D. 39 in.

Answer 1

B. 9 in

Explanation:

The area covered by the fabric (
`A`) is represented by the following formula:

`A = l^(2)`

Where
`l` is the side length of the canvas, measured in inches, and which is now cleared:

`l = √(A)`

If
`A = 77.8\,in^(2)`, then:

`l = \sqrt{77.8\,in^(2)}`

`l \approx 8.82\,in`

Which corresponds to option B.
