Question

A building has 4 stories that are each 15 feet high. A scale drawing has the height of the building at 5 inches.

Answer 1

1: 144 because 
4 * 15 = 60 ft total height = 720 in total height
5: 720 = 1: 144

Answer 2

Answer:

The correct scale value is 1:12.

Step-by-step explanation:

Height of the building in drawing ,h= 5 inches

Given that a building has 4 stories that are each 15 feet high,

So, actual height of the building ,H= $4\times 15 feet = 60 ft$

Scale factor = $\frac{h}{H}$

$=\frac{5}{60}=\frac{1}{12}= 1:12$

The correct scale value is 1:12.
