Question

Find the area of triangle whose base is $5.5\mathrm{cm}$ and height is $3\mathrm{cm}$ . Find the area of triangle.

Answer 1

Calculate the area of triangle.

$\mathrm{Area}\mathrm{of}\mathrm{triangle}=\frac{1}{2}\times \mathrm{base}\times \mathrm{height}$

Base is given $5.5\mathrm{cm}$

Height is given $3\mathrm{cm}$

$$\begin{gathered} \mathrm{Area}\mathrm{of}\mathrm{triangle}=\frac{1}{2}\times 5.5\times 3 \\ =\frac{16.5}{2} \\ \mathrm{Area}\mathrm{of}\mathrm{triangle}=8.25{\mathrm{cm}}^2[\mathrm{On}\mathrm{dividing}16.5\mathrm{by}2] \end{gathered}$$

Hence, $8.25{\mathrm{cm}}^2$ is the area of the triangle.
