What is the area of the regular pentagon below

nordsb [41]

Answer:

Step-by-step explanation:

By definition, all sides of a regular polygon are equal in length. If you know the length of one of the sides, the area is given by the formula:

$A=\dfrac{s^2\cdot n}{4\tan \frac{180^{\circ}}{n}},$

where s is the side length, n is the number of sides.

In your case, s=20 ft, n=5,so

$A=\dfrac{20^2\cdot 5}{4\tan \frac{180^{\circ}}{5}}=\dfrac{400\cdot 5}{4\tan 36^{\circ}}=\dfrac{500}{0.73}\approx 688.2\ ft^2$
