It all starts to make sense

Why base times height?


The same formula works for rectangles, squares, and parallelograms, because they all have two pairs of sides that are the same length.


Tennessee...

The length of TN is about 440 miles and it is about 120 miles long.

                           440 * 120 = 52,800


An approximate estimate of TN's area is 52,800 square miles.
The actual area is 42,146 square miles.
