Question

A scale on a blue print drawing of a house shows that 6 centimeters represents 3 meters. What number of centimeters on the blue print represents an actual distance of 27meters?

Answer 1

54 cm

Explanation:

Measures are proportional on a scale drawing:

drawing measure : actual measure = 6 cm : 3 m = x : 27 m

The value on the right of the x ratio, 27, is 9 times 3, so the value of x will be 9 times 6 cm.

54 cm on the blueprint represents an actual distance of 27 meters.
