What is the area of the regular octagon with a side length of 10 m and an apothem of 12.1 m?
a.
242 m2
b.
363 m2
c.
484 m2
d.
968 m2
here is a picture if you need it.

A = 2 * a^2 * (1 + sqrt 2)

Where 'a' is the side length.

A = 2 * 10^2 * (1 + sqrt 2)

A = 2 * 10^2 * 2.41421356

A = 2 * 100 * 2.41421356

A = 200 * 2.41421356

A = 482.842712

Therefore, the closest one is C.

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
