This isn't too difficult since we're given the apothem and the side length of the pentagon.
We can calculate the area of the pentagon using this formula:
A=5/2*a*s
a=apothem length
s=side length
Plug in values for "a" and "s":
A=5/2*5.5*8
A=110
So the area of the regular polygon is 110 cm^2
Hope this helped. It's my first time helping out on Brainly.
