Required:

Explanation of the area of a triangle.

Explanation:

Definition of Area :

Amount of space within the closed surface of of a 2D shape.

Area of a triangle:

Amount of space within the given triangle is the area of a triangle.

Formula to find the area of a triangle:

$\text{Area of a triangle=}\frac{1}{2}\times Base\times Height\text{ square units}$

For Example we take one triangle with dimension:

Base of the above triangle is BC and height of a triangle is AD.

$\begin{gathered} BC=10cm\text{ } \\ AD=6cm \end{gathered}$$\begin{gathered} \text{Area of a triangle=}\frac{1}{2}\times Base\times Height \\ =\frac{1}{2}\times10\times6 \\ =30cm^2 \end{gathered}$
