A couple wants to install a square mirror thats has an area of 500 square inches. to the nearest tenth of am inch what length of wood trim is needed to go around the mirror?

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 = s 2

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
