Marizza181 [45]

A couple wanted to install a square mirror that has:

Area of the mirror = 500 square inches.

x = nearest tenth of an inch , length of wood needed

s = sides of square


Area = s2

500 (area) = s2  | √

x = √500

=> √ 5 x 100

=> √ 5 x √100

=> 10 √ 5

=> approximately 22.4


Since we’re looking for the nearest tenth of decimal place value, the answer is approximately 22.4
