Based on the dimensions of the regular pentagon, the approximate area can be found to be 342 cm².
<h3>How to solve for approximate area?</h3>
The area of the pentagon can be found by the formula:
= 5 x 1/2 x Length of pentagon x apothem of pentagon
The apothem is:
= √(12² - (14.1/2)²)
= 9.7
The approximate area of the pentagon is therefore:
= 5 x 1/2 x 14.1 x 9.7
= 342 cm²
