Praxis 5511 Practice Question
On a county map, 1/4 inch represents 1 mile. If a square region on the map has a perimeter of 6 inches, what is the actual length of a side of the square region, in miles?
Correct Answer: C
Rationale: To find the actual length of a side of the square region, start by calculating the side length from the perimeter. A square's perimeter is given by \( P = 4s \), where \( s \) is the side length. With a perimeter of 6 inches, \( s = \frac{6}{4} = 1.5 \) inches.
Next, convert inches to miles using the scale provided: 1/4 inch equals 1 mile. Therefore, 1.5 inches equals \( 1.5 \div 0.25 = 6 \) miles.
Option A (1.5) misrepresents the actual length by not converting to miles. Option B (3) incorrectly assumes a different conversion. Option D (24) overestimates the conversion, misunderstanding the scale. Thus, the actual length of a side is 6 miles.
