Answer:

666.6667 feet²

Step-by-step explanation:

So.

Since the scale is 1 : 20, we can do 4 x 20 and 5 x 20, Which is 80 and 100.

Find area: 80 x 100 = 8000 we can just add 2 zeros to 80 since it's multiplying by 100.

So it's 8000in²

Then we do 8000 in to feet.

Which is ≈ 666.6667feet

btw it asked for feet so we give them FEET
