Composite number. 69=3×23
The formula for solving the area of a regular decagon is shown below:
A=(5/2)a²√(5+2√5)
where "a" refers to the measurement of the side on which in this problem, it is equal to 9.3 units
We can proceed in solving for the area and the solution is shown below:
A=(5/2)*(9.3)²√(5+2√5)
A=665.47 square units
The answer is 665.47 square units.
