Question

Please help me with this

Answer 1

`\huge\boxed{A=675}`

Explanation:

`A=(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=(1)/(2)(15)(18)(5)=(1350)/(2)=675`

Answer 2

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,

`A=(1)/(2)(15)(90)`

so the area is 675 units squared.
