Final answer:
To make a scale drawing of a 72 feet by 108 feet building using a scale of 1 inch represents 12 feet, you would use dimensions of 6 inches by 9 inches.
Step-by-step explanation:
To make a scale drawing of a building that is 72 feet by 108 feet, we need to determine the dimensions on the scale drawing. Given that 1 inch represents 12 feet, we can set up the following ratios:
Width ratio: 1 inch ÷ 12 feet = x inches ÷ 72 feet
Length ratio: 1 inch ÷ 12 feet = x inches ÷ 108 feet
Solving for x in each equation, we find:
x = 6 inches for the width
x = 9 inches for the length
Hence, the dimensions to use for the scale drawing of the building would be 6 inches by 9 inches (option A).
