Find the area of a regular octagon whose side length is 4.7 in. and the apothem is 6.5 in

For this case we have by definition, that the area of an octagon is given by:

Where:

p: perimeter

a: apothem

We have that the perimeter is given by the sum of the sides of the octagon:

Substituting:

So, the area of the octagon is

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
