# Area of the polygon using apothem calculator

To calculate the area of a polygon using apothem, you need to know the length of the apothem and the number of sides of the polygon. Here’s the formula:

**Area = (1/2) x apothem x perimeter**

Where:

**apothem is the distance from the center of the polygon to the midpoint of a side****perimeter is the total length of all sides of the polygon**

### To use the calculator, follow these steps:

- Input the length of the apothem in the designated field
- Input the number of sides of the polygon in the designated field
- Input the length of each side of the polygon in the designated field (if known), or leave it blank
- Click on the “Calculate” button
- The area of the polygon will be displayed

Note: If you don’t know the length of each side, you can still calculate the perimeter by multiplying the number of sides by the length of one side.
