Can someone help me find the area of this triangle?
I looked it up and it talked about Heron’s formula or something like that, but we haven’t learned that at all in my class so I didn’t use it because why would my teacher give me something I haven’t learned, you know? Anyways, I have no idea how to solve for this triangle’s area. Can someone help? Thanks!
I also know that the area is 1/2bh but what would be the height in this case?
The numbers are 22ft, 18ft, and 33ft in case that helps
I mean 24ft lol

With the 33 foot side as the base
Use Law of Cosines to find the angle opposite the 18 foot side
18² = 24² + 33² - 2(24)(33)CosA
Work that through and find
CosA = 0.84659
<A = 32.157º
Now you can find the height
Sin A = opp/hyp
Sin 32.157º = height/24
h = 24 * Sin 32.157º
h = 12.77
A = (1/2)bh
A = 210.7 ft³ <––––––

i cant read the numbers on the sides. I guess no one else can either.

The height looks to be 220 in your fuzzy pic. It's half base x height just to be clear.
