Area of a Triangle | MathHelp.com

Need a custom math course? Visit www.MathHelp.com.
This lesson covers the area of a triangle. Students learn that the formula for the area of a triangle is 1/2 times base times height, so the area of a triangle that has a base of 9 meters and a height of 4 meters is 1/2 times 9 times 4, or 1/2 times 36, or 18 square meters.

Well, what if we don’t know the perpendicular height??

[@simpleman283]

Of the 181 comments, only one other person noticed a flaw in this triangle.
You can have a 18, 10, 14 triangle, but the height will not be 8.
However, the basic lesson is good.

I do it a bit different I do B•H / 2 b x h over 2
18 • 8 = 144 then I divide the 144 by 2 the bigger number inside and the 2 outside
2/144 which gives me 72in²

She was serious at the start but that creepy smile an tha end is cold

[@adamsjay212]

I would only cut the base in half if it’s a big number

[@T-Rex_Prime]

A=((P^2)*sin(x)*sin(y)*sin(z))/(2*(sin(x)+sin(y)+sin(z))^2)
where A is the area of triangle, P is the perimeter and x,y,z are the 3 angles of the triangle.
This equation works for all triangles.
Please check video on my channel for derivation of this formula.

Me learned the formula in class when i reach home i already forgot it 🙄

How do you get 9 from 1.2*18?

[@punishedsnake6141]

The formula is half of the base times height. So not 1.2 but .5...Hope this helps.

[@OND30]

Its not 1.2 its 1/2(1÷2)

[@noxoloradebe3751]

Its different in many countries because I got 1/2x8=4 which she said it's 8

[@alecalderin397]

Older one was more practical and applicable

1/2 x (10 inch base x 14 inch height) = 70 in square?

[@Dharmik_daGOAT]

It makes more sense than your life at least 😂

[@simpleman283]

That would be true if this was a right triangle, but it is not.
That is why she used the height.
Although I did find a flaw in her triangle, the basic concept here is good.
