Answer 1

Given:

Area of a triangle

Required:

Explanation of the area of a triangle.

Step-by-step 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=}(1)/(2)* Base* 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=}(1)/(2)* Base* Height \\ =(1)/(2)*10*6 \\ =30cm^2 \end{gathered}`
