Question

PLEASE HELP

A square room has an area of 30 square feet. To the nearest tenth of a foot, what is the length of
one side of the room?

Answer 1

5.5 inches

Explanation:

1) the formula to find the area of a square is l^2= area and l=length

in this case we already know the area but not the length

so we have to find the square root of 30 as the opposite operation needs to be used to find the missing number

so

√30= 5.47

5.47 rounded= 5.5

the length of one side is 5.5 in
