A house painter was told by his boss to purchase enough paint to cover 75 square feet to finish a project. The house painter hap
pens to know that the surface is square. How long is each of side of the surface? (Recall that the area of a square is calculated by 2003-04-02-00-00_files/i0160000.jpg, where l is the length of one side.) A.

B.

D.

It must be noted that the area of the square is calculated through the equation, A = s² where A is area and s is the measure of one side of the square. To determine the measure of one side of the square, we simply have to get the square root of the area, s = √A Substituting the known value, s = √75 ft² = 5√3 ft ≈ 8.66 cm Thus, the answer to this question is approximately 8.66 cm.
