Hi

the scale of a map is 3/4 inch=12 miles.

Let x represent number of miles 1" represents

Sets Up the Proportion

 %283%2F4%29%2F12+=+1%2Fx    |Cross Multiplying to solve

       (3/4)x = 12

            x = (4/3)12

            x = 16mi

What is the area, in square miles, of a plot represented on this map by a square whose side is 1 inch  

       (16mi)^2= 256 Mi^2
