There are different formulae, depending on what you DO know. Here you will find several: http://en.wikipedia.org/wiki/Triangle#Computing_the_area_of_a_triangle
You find the height by using Pythagoras' theorem and then 0.5*base*height = area.
Without knowing its base its almost impossible to give a correct answer.
-- Imagine what you have if you slice the triangle in half along the height ...-- You have a right triangle. One side of it is 1/2 of the base, and one side isthe height.-- The slanting side is the hypotenuse of the right triangle, and knowing whatyou know about right triangles, you can calculate its length.-- Once you do that, you have the lengths of all three sides of the original triangle,and you can calculate the perimeter.

To find the height of a triangle without knowing the base or area, you would typically need additional information, such as the lengths of the sides or angles. If you have the lengths of all three sides, you can use Heron's formula to calculate the area and then derive the height. Alternatively, if you know the angles, you can use trigonometric functions in conjunction with the side lengths to find the height. Without any of this information, it's impossible to determine the height directly.

I'm pretty sure that only works if it is an isosceles right triangle. In that case, use the Pythagorean theorem to calculate the base and height knowing only the hypotenuse. A2 + B2 = C2. A=B= height= base. C= hypotenuse
something
The area of a triangle is base x height / 2. Height should be perpendicular to base.
It's simple. Measure it!
The answer depends on what information you do have about it.
It is impossible to find the area of a triangle with no height, if the triangle had no height it would not even be a triangle, just a angle.
the equation for a triangle is 1/2base*height knowing that it's a simple equation solving for a single unknown.
The area of every triangle is 1/2 of (base x height).Knowing that, you can now find the area of any triangle,including this one, on your own.
