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.
