Joseph completely covered the floor of his square office with carpet. He used 148 ft2 of carpet. Which measurement is closest to the length of one side of Joseph’s office in feet?

Question

A. 11 ft
B. 27 ft
C. 12 ft
D. 74 ft

Answer 1

The area of a square is given by side squared, so to find the length of one side of the office, we need to find the square root of the area. Taking the square root of 148 is approximately 12.166. Rounding to the nearest whole number, the length of one side of Joseph's office is closest to 12 ft. So, the correct answer is (C) 12 ft.
