Answer:

640 feet²

Step-by-step explanation:

The scale drawing has length = 8 in and width = 5 in

Actual length of floor = 32 feet

Scale is 8 in : 32 feet or 1 in: 4 feet

So for every inch we multiply by 4 to get the actual value in feet

Since the scale width = 5 in, the actual width in feet = 4 x 5 = 20 feet

The area = length x width = 32 x 20 = 640 feet²
