Question

A regular pentagon has side lengths of 14.1 centimeters and an apothem with length 12 centimeters.

Answer 1

Answer:

The approximate area of the regular pentagon is 423 sq.cm.

Step-by-step explanation:

Formula of area of regular pentagon =$\frac{Pa}{2}$

P=Perimeter of pentagon

a=Apothem

Side of pentagon = 14.1 cm

Perimeter of pentagon =$5 \times Side = 5 \times 14.1=70.5$

Apothem=12 cm

Area of regular pentagon = $\frac{70.5 \times 12}{2}=423 cm^2$

Hence the approximate area of the regular pentagon is 423 sq.cm.
