Praxis 5003 Practice Test Practice Question
The floor of a closet is a square with a perimeter of 18 feet. How many square feet of flooring will be needed in order to put a new floor in the closet?
Correct Answer: C
Rationale: To determine the area of the closet floor, first, calculate the side length of the square. The perimeter of a square is given by the formula \( P = 4s \), where \( s \) is the side length. With a perimeter of 18 feet, the side length is \( s = \frac{18}{4} = 4.5 \) feet. The area of a square is calculated using \( A = s^2 \). Thus, \( A = (4.5)^2 = 20.25 \) square feet.
Option A (4.5) represents the side length, not the area. Option B (9) is incorrect as it does not correspond to any calculation related to the area. Option D (324) is far too large, likely resulting from a misunderstanding of the units or squaring the perimeter rather than the side length.
