Question

Find the area of the regular polygon. Give the answer to the nearest tenth.

pentagon with radius 8 m
A) 304.3 m2
B) 152.2 m2
C) 30.4 m2
D) 154.2 m2

Thanks!

Answer 1

is it possible to solve this since we dont know the length of each side of the pentagon?

Answer 2

How about this:
there are 5 sides of the pentagon.
the radius (also the height of the triangle) is 8
area of a triangle is half of base times height.
we have 8 * .5 * 5 which is 20

Can we eliminate the answers that cant be divided by 20?

Just scrambling here.
