The relationship cannot be determined from the information given.

Answer 1

ugh geometry :/

Answer 2

i know! :/ i hate it!

Answer 3

if the shape is regular then split it into x amount of triangles and find the area of a triangle and add all the triangles to find area of the shape

Answer 4

Column A
A = 1/2 * a* p where a is the apothem and p is the perimeter of the regular octagon. A regular octagon has 8 sides that are the same length. So, the perimeter is 8*4 = 32.
A = 1/2 * 4 * (4*8)
A = 2*32 = 64

Column B
A = 1/2 * a* p where a is the apothem and p is the perimeter of the regular hexagon. A regular hexagon has 6 sides that are the same length. So, the perimeter is 6*4 = 24.
A = 1/2 * 4 * (4*6)
A = 48

So, the answer in Column A is all the time larger than the answer in Column B. Hence, A is the answer.
But, L@@K,
there's no need to do all that work.
Look at the regular octagon equation: A = 1/2 * 4 * (4*8)
Look at the regular hexagon equation: A = 1/2 * 4 * (4*6)
They differ by one number. (4*8) versus (4*6)
The 8 in the formula for Column A is bigger than the 6 in the formula for Column B so without doing any calculations, we know that Column A or A is the answer.

Answer 5

okay, thank you so much! :)
