I can calculate the area of regular polygons using given formulas.
- 1
The formula for the area of a regular polygon is Area = ½ * apothem * perimeter, where the apothem is the distance from the center to a side at a right angle.
- 2
To find the area of a regular polygon, you can multiply ½ * apothem * perimeter, where the perimeter is the sum of all the sides, or the side length multiplied by the number of sides.
- 3
When solving for a missing variable, such as the apothem, plug in the known values into the formula Area = ½ * apothem * perimeter and solve the resulting equation using algebraic methods.
