. Use the formula
s

√
A
to find the length of one side of the picture. Round your answer to the nearest tenth of a inch.

Answer 1

`s=8.1\ in`

Explanation:

we know that

The area of a square is

`A=s^(2)`

Solve for s

`s=√(A)`

where

s is the length side of the square

A is the area of the square

In this problem we have

`A=65\ in^2`

substitute in the formula

`s=√(65)`

`s=8.06\ in`

Round to the nearest tenth of a inch

`s=8.1\ in`
