Question

a square floor has an area of 196 square feet. How long is each edge of the floor?

Answer 1

a square means that it's a rectangle with all four sides equal in length. So, since area for square is side squared (s²):

 

s² = 196

 

use a calcuator to get the square root of 196 which is 14.

 

so length is 14 feet.
