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
