Answer:
The area of the actual building lot is [tex]5,040\ ft^2[/tex]
Step-by-step explanation:
Scaling
The scaled rectangular building measures 7 feet by 5 feet. We know both magnitudes were scaled by a factor of 12, thus the real dimensions of the house to be built are 7*12=84 feet, and 5*12=60 feet.
The area of the actual building lot is calculated by:
[tex]A=84\ ft*60\ ft=5,040\ ft^2[/tex]
The area of the actual building lot is [tex]5,040\ ft^2[/tex]
