A square with an edge of exactly 1 cm has an area of: A)10^-6 m² B)10^-4 m² C)10^-2 m² D)10² m² E)10⁴ m²

Question

Quizplus · Accepted Answer

The formula for the area of a square is A = s^2, where A is the area and s is the length of a side. In this case, s = 1 cm, so A = (1 cm)^2 = 1 cm^2. However, the answer choices are in meters, so we need to convert. 1 cm^2 is equal to (1/100)^2 m^2 = 0.0001 m^2. Therefore, the answer is 10 times this, or 0.001 m^2, which is equivalent to 10*-4 m^2. The only answer choice in this format is B.
