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

Answer 1

area of a square = s²

s² = 196

square root both sides

√196 = 14

s = ±14

Since you are asked the length of a side (length can never be negative, remember that in application dealing that include solving), your only answer will be +14. 14 meters is the length of each side of the square.
