Assuming the given sides are the two legs, use the Pythagorean theorem:

hypotenuse = sqrt(18^2 + 80^2) = sqrt(324 + 6400) = sqrt(6724) = 82.

Perimeter = 18 + 80 + 82 = 180 inches.

(If instead 80 were the hypotenuse, the other leg would be sqrt(80^2 − 18^2) ≈ 77.964 and the perimeter ≈ 176.0 in.)
