On a scale of 1 inch = 50 feet, what is the area of a location that is
10000 square feet?

Hi David,

Thanks for your question.  If I understand what you want, you can
think of it this way:

10000 square feet is a square 100 feet on a side (100*100 = 10000); so
on a map on which 1 inch is 50 feet, the square would be 2 inches on a
side. Hence, the map square would have an area of 4 square inches.

So, if you are given A square feet, the the area on the map would be

(sqrt(A)/50)^2 = A/2500 square inches.
