Find the area of the non-right triangle.
8 ft.
4 ft.
9 ft.
To find the area of a non-right triangle, we can use Heron's formula:
s = (8 + 4 + 9) / 2 = 21/2 = 10.5
Area = √(s(s-8)(s-4)(s-9))
Area = √(10.5(10.5-8)(10.5-4)(10.5-9))
Area = √(10.5*2.5*6.5*1.5)
Area = √(255.9375)
Area ≈ 15.998
Therefore, the area of the non-right triangle is approximately 15.998 square feet.
