2) Since you have the lengths of all three sides, you do not need the height, h, to get the area. If you use h, you need to know which side it is perpendicular to.

The half-perimeter is

s = (1/2)(a + b + c) = 16.5 inches.

The area is sqrt[s(s-a)*(s-b)*(s-c)] = __

It does not agree with any of your choices
