A building has 4 stories that are each 15 feet high. A scale drawing has the height of the building at 5 inches
Which of the following is the correct scale?
1:144
1:12
5:60
1:72

The correct scale is 1 : 144

Solution:

A building has 4 stories that are each 15 feet high

Therefore,

Total height of building =

We know that,

1 feet = 12 inches

60 feet = 60 x 12 = 720 inches

A scale drawing has the height of the building at 5 inches

Therefore,

Scale ratio = 5 inches : 720 inches

Reducing to lowest terms,

Scale ratio = 1 : 144

Thus option A is correct

The answer is a good luck
