Code to add this calci to your website

#### Formula:

S = (5 / 2) L x A
**Where,**
S = Surface Area of a Pentagon
L = Length of Side
A = Apothem
### Example:

Calculate the surface area of a pentagon with the length of the side of 50 cm and the apothem length of 20 cm.

#### Solution:

S = (5 / 2) 50 x 20

= 2500 cm²
