Answer:
Step-by-step explanation:
You have everything you need to fill in the formula and find the area. The apothem is 15 and the perimeter is 18(5) which is 90. Therefore,
[tex]A=\frac{1}{2}(15)(90)[/tex]
so the area is 675 units squared.
[tex]\huge\boxed{A=675}[/tex]
[tex]A=\dfrac{1}{2}asn\\\\a-\text{apothem}\\s-\text{side length}\\n-\text{number of sides}\\\\\text{We have:}\\\\a=15\\s=18\\n=5\\\\\text{Substitute:}\\\\A=\dfrac{1}{2}(15)(18)(5)=\dfrac{1350}{2}=675[/tex]
