Question

Robinson ' s square shaped air conditioner covers 144 feet of area of his room. what is the length of any side?

Answer 1

If it's a square, then the sides must be equal. So, find the square root of 144, which is 12. To make sure you are correct, you can find the area of a square with 12 feet sides, which is 144. 12 is correct. 

Answer 2

Hey there,
Area = 144 square feet
Length = square root 144 square feet 
            = 12 cm

Hope this helps :))
