Answer 1

To find the actual area of the floor in square feet, we need to first determine the scale factor between the drawing and the actual floor.

Scale factor = Actual length / Drawing length
Scale factor = 32 feet / 8 inches
Scale factor = 4

Now, we need to find the actual width of the floor by multiplying the drawing width by the scale factor:
Actual width = 5 inches * 4 = 20 feet

The actual area of the floor is:
Actual area = Actual length * Actual width
Actual area = 32 feet * 20 feet
Actual area = 640 square feet

Therefore, the actual area of the floor is 640 square feet.
