Question

Construction workers are doing a building project using floor plans that have a scale of 1 cm to 2 m. On the floor plans, a corridor is shown with a length of 9 cm. How many meters long will the actual corridor be?

A. 9 m
B. 10 m
C. 18 m
D. 36 m

Answer 1

The actual corridor will be 18 meters long based on a scale of 1 cm to 2 m and a floor plan length of 9 cm.

Step-by-step explanation:

If construction workers are using floor plans that have a scale of 1 cm to 2 m, and a corridor is shown on the floor plans with a length of 9 cm, then the actual length of the corridor can be calculated by multiplying the scale factor with the measure on the plan. To determine the actual length, you would perform the following calculation:

9 cm × 2 m/cm = 18 m

Therefore, the correct answer is C. 18 meters.
