To find the area of a triangle, you can use the formula:

$\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}$

Where:

• Base is the length of one side of the triangle, typically the bottom side.
• Height is the perpendicular distance from the base to the opposite vertex.

Example:

If the base of a triangle is 8 cm and the height is 5 cm, the area would be:

$\text{Area} = \frac{1}{2} \times 8 \times 5 = 20 \, \text{cm}^2$

If the height is not given directly, other formulas might be used based on the available information, such as Heron's formula when the side lengths are known.

Tip: Always ensure the height is perpendicular to the base when using the basic area formula.
