Question

question 11
a blueprint uses a scale of 1 cm=2.5 ft.
if a room measures 6.8 cm on the blueprint, what is the actual length?
17 ft
14 ft
10 ft
20 ft

Explanation:

Step1: Identify the scale factor

The scale is \(1\) cm = \(2.5\) ft, so each cm on the blueprint represents \(2.5\) ft in actual length.

Step2: Calculate actual length

To find the actual length, multiply the blueprint length (\(6.8\) cm) by the scale factor (\(2.5\) ft/cm). So, \(6.8\times2.5 = 17\) ft.

Answer:

17 ft
