Praxis 5511 Practice Test Practice Question

In an architect's scale drawing, the length of a kitchen is 4.5 centimeters. The actual length of the kitchen is 15 feet. If the width of the kitchen in the scale drawing is 2.7 centimeters, what is the actual width of the kitchen?

Correct Answer: B

Rationale: To determine the actual width of the kitchen, we first find the scale of the drawing. The length in the drawing (4.5 cm) corresponds to the actual length (15 feet). The scale factor is calculated as follows: 15 feet / 4.5 cm = 3.33 feet per centimeter.

Next, we apply this scale to the width of the kitchen in the drawing (2.7 cm). Multiplying 2.7 cm by the scale factor gives us 2.7 cm × 3.33 feet/cm = 9.0 feet, confirming option B as the correct answer.

Options A (8.1 feet), C (10.3 feet), and D (12.3 feet) do not align with the calculated scale, resulting from incorrect multiplication or misunderstanding of the scaling process.
