Sam purchased 625 square feet of carpet for his bedroom, which is shaped as a square. What are the dimensions of his bedroom?
A. Each side of the bedroom has a length of 25 feet.
B. Each side of the bedroom has a length of 156.25 feet.
C. Each side of the bedroom has a length of 390,625 feet.
D. Each side of the bedroom has a length of 312.5 feet.
The area of a square is calculated by multiplying the length of one side by itself. Therefore, to find the length of one side of the bedroom, we need to find the square root of 625.
√625 = 25
Therefore, each side of the bedroom has a length of 25 feet.
So, the correct answer is A. Each side of the bedroom has a length of 25 feet.
