Write an expression that represents the perimeter of a triangular garden that has one side 2 inches less than three times wider than the height (h) a second side that equals the height (h) and a third side that is 18 units long.

answer; ///i believe that the correct answer is (the south);

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
