The area of a regular pentagon can be calculated using the formula A = 1/2 * Perimeter * Apothem.
First, calculate the perimeter of the pentagon:
Perimeter = 5 * side length = 5 * 20 = 100 inches
Now, plug in the values into the formula:
A = 1/2 * 100 * 14 = 50 * 14 = 700 square inches
Therefore, the correct answer is:
B. 700 in^2
