Scale drawing
From the question, we are to determine the how tall the proposed skyscraper is in meters
From the given information,
The scale of the model is
1 in : 7.2 m
and
The model is 2 ft tall
First, convert 2 ft to inches
NOTE: 1 foot = 12 inches
∴ 2 feet = 2 × 12 inches
= 24 inches
Now,
If 1 inch represents 7.2 m
Then,
24 inches will represent 24 × 7.2 m
24 × 7.2 m = 172.8 m
Hence, the proposed skyscraper is 172.8 m tall
