Answer:
see explanation
Step-by-step explanation:
The area (A) of a regular decagon ( 10 sided ) is calculated as
A = 0.5 × perimeter × apothem
Here side length = 3.25, hence perimeter = 10 × 3.25 = 32.5 m, thus
A = 0.5 × 32.5 × 5 = 81.25 m²
Regular decagon
Solve for areap
A=5/2a²√5+2√5
apothem
5
No.of Sides of Polygon
Length of each side
3.25
Unit : in
Area of Polygon = 40.625in2
Formula
The following mathematical formula is used in this regular plygon area calculator to find the area from the given input value of apothem, number of sides & length of side.
Rectangle Polygon Area A = (1/2) Apothem x No. of Sides x Length of side
