Question

JoAnn covered a square wall using 84.5 square feet of wallpaper. What whole number of feet is the closest to the height of the wall?​

Answer 1

height ≈ 9 feet

Explanation:

the wall is a square, so the length and width are equal

l • w = area

l • w = 84.5

l = w

l = √84.5

= 9.19238815543

≈ 9 feet
