Eighty percent of a roof, or 2800 square feet of the roof, has been re-shingled. what is the total area of the roof? a. 22,400 sq ft b. 2240 sq ft c. 3500 sq ft d. 35000 sq ft

Given that "80% of the roof" is same as "2800 square feet of the roof".

Let's consider total area of roof = X square feet.

Then "80 percent of X" = "2800 square feet".

So total area of the roof would be 3500 square feet.

Hence, option C is correct i.e. 3500 square feet.
