Question

Becky drew a scale drawing of the high school. The scale she used was 1 millimeter : 5 meters. The parking lot is 5 millimeters in the drawing. How wide is the actual parking lot?

A) 1 meter
B) 5 meters
C) 10 meters
D) 25 meters

Answer 1

To find the actual width of Becky's scale drawing of a parking lot, we multiply the drawing size in millimeters (5 mm) by the scale factor (5 meters/mm), yielding an actual width of 25 meters (option D).

Step-by-step explanation:

The student is asking about how to determine the actual size of a parking lot given its scale size in a drawing and the scale factor. Becky used a scale of 1 millimeter : 5 meters and the parking lot in the drawing measures 5 millimeters. To determine the real-world size of the parking lot, we multiply the drawing size by the scale factor.

To calculate:
Actual width of the parking lot = Drawing size in millimeters × Scale factor metres/millimeter
Actual width of the parking lot = 5 mm × 5 meters/mm
Actual width of the parking lot = 25 meters.

Therefore, the actual width of the parking lot is 25 meters, which corresponds to answer choice D.
