A gallon of stain can cover a square deck with an area of 300 square feet. About how long is each side of the deck? Round your answer to the nearest foot.

Answer :

The area of a square = length of a side^2
A=s²
300=s²
√300 = s
s is about 17.3
Round to 17 feet
A=s^2 , A= LxW , A=300 You have to find the square foot of 300 that is 17.3
