Answer 11

there you go

Answer 12

well then
notice the apothem there? the line going from the side to the center
also
notice the length of one side? keep in mind that a HEPTAgon, means 7 sides

if there are 7 sides, what's the perimeter of it?

now, with that in mind, recall that \(\bf \textit{area of a regular polygon}=\cfrac{1}{2}\cdot apothem\cdot perimeter\)

Answer 13

That's pretty cool. I didn't know there was a formula for the area of a regular polygon given the apothem.

Answer 14

so the perimter is the base number

Answer 15

Conventionally, and less efficiently, I was thinking of breaking up that polygon into several triangles. Measure one of them, and multiply it by 6.

Answer 16

i think is a but make sure first

Answer 17

kk

Answer 18

No, the perimeter is teh base multiplied by 7.

Answer 19

perimeter of anything, is "how lengthy it is"
the heptagon has 7 sides, add them all up, and that's how lengthy it's, and thus, that's its perimeter

Answer 20

ohh

Answer 21

so the perimeter is 145.6

Answer 22

so the awnsewer is A
