asked 07/14/20Polygons (Finding Apothem)
I am trying to find the apothem for a nonagon with 8 food sides.
I understand the formula for regular polygon to be : Area= 1/2(apothem)(perimeter)
For my problem the perimeter is 72, though I am not sure how, with this information, I can find the measure of the apothem.
Thanks,
Brian
