No.
The best known formula for the area of a triangle is 1/2*base*height
where height is the vertical distance from the base to the third vertex.
But there are other formulae, depending on the information available.
eg 1/2*a*b*sin(C)
where a, b are the lengths of two sides and C is the angle between them. Sin is the trigonometric function, sine.
or sqrt[s*(s-a)*(s-b)*(s-c)] where a, b and c are the lengths of the three sides and s = (a+b+c)/2
There are others, more complicated ones.

How do find area of triangle?
1/2bh b=base h=height To find the are of a triangle,you have to multiply the base times height and divide the answer by 2. To find the area of a triangle you need to multiply all the sides of the triangle and then divide by 2.
How do you find volume and area of a triangle?
A triangle has no volume - it is a 2-dimensional shape only. To find the area, multiply the base times the height, then divide by 2. The base is any side of the triangle; the height must be measured perpendicular to the base.
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 height of a triangle if you only have the base and area?
Multiply the area by 2 and divide by the base
Why is the formula for area of a triangle and area of a trapezoid are what they are?
area triangle = 1/2 base times height area trapezoid = 1/2 (sum of bases) times height
How do you get the area of triangle?
Multiply 1/2 times the base times the height. A-1/2bh
How do find area of triangle?
1/2bh b=base h=height To find the are of a triangle,you have to multiply the base times height and divide the answer by 2. To find the area of a triangle you need to multiply all the sides of the triangle and then divide by 2.
Volume of a triangle?
A triangle is a two-dimensional shape (flat), so it has area, but not volume. The area of a triangle is half the height times the base. Multiply the height times the length of the triangle's base, then divide by 2.
What is the equation for surface area?
with a tape measure To calculate the area of a rectangle, you multiply the length times the width. To calculate the area of a square, you multiply one side times another side. To calculate the area of a circle, you multiply the diameter times pi (that's 3.1416). To calculate the area of a triangle, you multiply the height times the base, and divide by 2.
How do you figure out the area for a triangle?
you multiply the length times the width and then divide by 2, the equation looks like this... LxS/2
Do you multiply for area?
It depends what you are trying to get the area of. For example, to find the area of a square or rectangle you multiply the length times the width. But to find the area of a triangle, you multiply the height times 1/2 of the base. So yes, you usually multiply to find area of a figure, but there may be more steps to the process.
How is the area triangle related to the area of a rectangle?
two right triangles = full rectangle That is - if you multiply height times base of a triangle, the area will be 1/2 of a rectangle having the same height, and a width the same as the triangle base.
How do you find volume and area of a triangle?
A triangle has no volume - it is a 2-dimensional shape only. To find the area, multiply the base times the height, then divide by 2. The base is any side of the triangle; the height must be measured perpendicular to the base.
How do you get the area of a triangle to triangle cm and convert it to triangle millimeters?
To calculate the area of a triangle - divide the length of the base by 2, then multiply that figure by the height. If the measurements are in centimetres, once you have your area - multiply your figure by 100 and you'll have the area in millimetres.
How do you the area of a triangle?
To find the area of a triangle, multiply base x height and divide by two. Written as: A=bh/2
How do you find volume of a triangle?
Multiply the area of the base by the height of the object. The area of the base can be found by multiplying the length times the width of one of the faces.
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.
