# What is a formula of area of triangle?

## What is a formula of area of triangle?

So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.

What is a formula triangle?

Formula triangles are a tool to help students use equations without needing to rearrange them. In the example here it’s the volume: cover up V to see the required equation is moles divided by concentration. Or if you want the number of moles, cover up the n and then, as c and V are side by side, multiply them together.

Who gave the formula for area of triangle?

In geometry, Heron’s formula (sometimes called Hero’s formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first.

### How find the area of a right triangle?

Area of one right triangle = 1/2 × l × w. We usually represent the legs of the right-angled triangle as base and height. Thus, the formula for the area of a right triangle is, Area of a right triangle = 1/2 × base × height.

How do I calculate volume of a triangle?

Calculating volume

1. Remember the formula for calculating volume is: Volume = Area by height. V = A X h.
2. For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.
3. So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

What is the formula for area of all shapes?
