I found that the  dimensions of Tennessee are 440 mi. x 120mi. By using the formula "A=lxw", I concluded that the approximate area of Tennessee is 52,800 sq. mi. This approximate answer is much higher in contrast to the state's exact area which is 42,144 sq. mi. The formula for finding the area of a square,rectangle,and parallelogram are the same because all of the shapes are parallelograms.
