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.

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.

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.

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.

Multiply 1/2 times the base times the height. A-1/2bh

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.

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.

you multiply the length times the width and then divide by 2, the equation looks like this... LxS/2

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.

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.

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.

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.

To find the area of a triangle, multiply base x height and divide by two. Written as: A=bh/2

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.

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.
