To find the area of a triangle using Heron's formula, first calculate the semi-perimeter (s) of the triangle:
s = (9 + 7 + 13) / 2 = 15
Then, use Heron's formula to find the area:
Area = √[15(15-9)(15-7)(15-13)]
Area = √(15*6*8*2)
Area = √1440
Area ≈ 37.95 inches squared
Therefore, the closest option is 40 inches squared.
