The formula for finding the height of an octagon from only one side is h=s(1 + the square root of 2). S is the length of one side. Your formula would be h=18(1 + the square root of 2).
h=18+18(the square root of 2)
h=18 + 25.4558
h=43.4558
Hope this helps!! :) And the decimal is rounded, just so you know ;). If your teacher likes everything in simplest radical form, then just don't convert the 18*the square root of 2 into a decimal and solve as you normally would.
P = 2(L + W)
P = 2(6.82 + 9.35)
P = 2(16.17)
P = 32.32 meters <==
We Know, distance = speed * time
d = 15.5 * 2.5
d = 38.75 miles
In short, Your Answer would be 38.75 miles
