Question

What is the area of a triangle with a base of 9units and a height of 7units ?

Answer 1

The area of a triangle is given by

`A=(1)/(2)\cdot b\cdot h`

Where b is the base and h is the height of the triangle.

Let us substitute the given values of base and height into the above formula

`\begin{gathered} A=(1)/(2)\cdot b\cdot h \\ A=(1)/(2)\cdot9\cdot7 \\ A=(63)/(2) \\ A=31.5 \end{gathered}`

Therefore, the area of the triangle is 31.5 square units.
