If the 7" and 18" are the two legs, then the hypotenuse is 19.313" (rounded).
If the 18" is the hypotenuse, then the missing leg is 16.583" (rounded).
More than one unique triangle exists with the given side lengths.
Depends on the height... Area = 1/2 bh 18 = 1/2 bh 36 = bh base could be factors of 36 like 2, 3, 4, 6, 9
