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

Respuesta :

Area of a square is length squared.
Let the length be x, then
[tex] x^{2} =40[/tex]
Therefore,
[tex]x= \sqrt{40} =6ft[/tex]
