You need to know the base and height of the triangle. Once you found these multiply together and divide by two.
if you know the two legs of the triangle, you can use the Pythagorean theorem to find the hypotenuse as the base. Then you use the formula to find the area of the triangle: 1/2 (pi) bh.
If you know the area, divide by the half the base. A = 1/2 b x hYou need to know at least one of its acute angles and then use trigonometry to find its height.The answer depends on what information about the triangle you do have.
First, you'd need to be absolutely sure of what a "3-D triangle" is. With the information given in the question, and the Math I know, I'm not there yet.
The area of the triangle is 1/2*bh. So if you know the height and the base just plug in the values.
Use either the Sine or Cosine rules depending on the information you know about the triangle.
If you know how to find the area of a triangle do the same thing and you will get the same answer.
It appears as if you already know the base.
You will need to know the height before you can calculate the base form the area.
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
You cannot since the information is not sufficient. Furthermore, a triangle does not normally have a slope.
in a triangle double area and divide by base in a rectangle divide area by base
area = 1/2 base * perpendicular height you can't find both the base and the height if you only know the area
