OpenStudy (acxbox22):

the formula for area of a regular polygon is A=1/2(perimeter)(apothem)

OpenStudy (acxbox22):

what is the perimeter?

OpenStudy (anonymous):

umm im not sure

OpenStudy (acxbox22):

an octagon has 8 sides with each side measuring 10 m so the perimeter=8 x 10

OpenStudy (anonymous):

so 80

OpenStudy (acxbox22):

yes now plug in 80 for perimeter and 12.1 for apothem into the equation and solve for area

OpenStudy (anonymous):

So D

OpenStudy (anonymous):

Or is it C
