Carlos has a square tablecloth with a total area of 48 square feet. Wich measurement is closest to the lenght of each side of the tablecloth in feet

If the total area is 48 square feet, and we remember that if s is the side length, then s^2 = 48. Round this off to the nearest perfect square: s^2 = 49, so s = 7 feet is a good approximation to the length of one side.

The correct is 44 because you estamate and 48 is close to 44
