Responses
The area of a regular pentagon can be calculated using the formula:
Area = (0.25 * √(5 * (5 + 2 * √5)) * (side)^2
Plugging in the given side length of 12in, we get:
Area = (0.25 * √(5 * (5 + 2 * √5)) * (12)^2 = 309.0 square inches
Therefore, the area of the regular pentagon with a side length of 12in is 309.0 square inches.
