Question

Please I need help!!! The local library asked Reese's art class to paint a mural on a wall of the library. For the background, they painted a large square and used enough paint to cover forty feet squared . How long is one side of the square rounded to the nearest whole number?

a.5ft
b.6ft
c.7ft
d.8ft

Answer 1

Area of a square is length squared.
Let the length be x, then

`x^(2) =40`
Therefore,

`x= √(40) =6ft`
