A regular polygon is a shape with equal sides and angles. Because of this, we can write the following equation to set two sides equal to each other:

Solving, we will get a in terms of b:

Now we can substitute a for (b+3) into our equation:

Therefore, the length of each side of this polygon is
.
Since the perimeter of the polygon consists of all five sides, the perimeter is:

Greatest to least:
74.01, 73.50, 73.05
It is B Because you are finding the intrest rate which means find the rate first hen subtract the actual rate to the interest rate<span />
