Using the given scale factor, the actual area of the barn with a length of 20 inches and breadth of 25 inches is calculated as 1280 square feet.
To find the actual area of the barn, we need to use the given scale factor. The scale is 5 inches = 8 feet. We can first find the actual dimensions of the barn by converting the blueprint dimensions using the scale factor.
For length:
Actual Length = Blueprint Length * (Actual Length Scale Factor)
Actual Length = 20 inches * (8 feet / 5 inches) = 32 feet
For breadth:
Actual Breadth = Blueprint Breadth * (Actual Breadth Scale Factor)
Actual Breadth = 25 inches * (8 feet / 5 inches) = 40 feet
Now, we can find the actual area of the barn:
Actual Area = Actual Length * Actual Breadth
Actual Area = 32 feet * 40 feet = 1280 square feet
Therefore, the actual area of the barn is 1280 square feet.
