First add the lengths of the three sides, a,b,c and divide by two (= half the perimeter).
Call that S.
Area = square root of (S*(S-a)*(S-b)*(S-c))
First the subtractions, then the multiplications and finally the square root.

What is the formula for area for a triangular prism without the height?
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.
How do you find the area of an equilateral triangle without knowing the height?
You find the height by using Pythagoras' theorem and then 0.5*base*height = area.
How do you find the area of a right triangle without the height?
you can't unless you measure it.
How do you find the area of a triangle without the base?
You need to measure how wide it is and the height of the triangle then multiply them together and the you get your answere.
How do you find the area and perimiter of a triangle?
To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.

How do you find the area of a triangle if you have base and height?
Area = 0.5*Base*Height
How can you find the height of a triangle if you have base and area?
The relation between the height of a triangle, its base and its area is given by: Area = 0.5 * Base * Height Therefore, we have: Height = (2 * Area)/ Base.
Do you have to miltiply to find the area of a triangle?
In order to find the area of a triangle, you need to multiply the base of the triangle with the height of the triangle and then halve your final answer.The formula is (Base x Height) / 2Using that, the area of a triangle can be found.Hope that helps.Jamz159
The height of a triangle is three feet longer than the base The area of the triangle is 35 square feet Find the height andbase of the triangle?

How you find the area of a triangle?
To find the area of a triangle, you have to multiply the base of the triangle and the height of the triangle, then divide the product of those numbers by two.
How do you find th area of triangle?
Area of a triangle = 0.5*base*perpendicular height
