Question

Find the area of triangle whose base is $8\mathrm{cm}$ and height is $3.5\mathrm{cm}$. Find the area of triangle.

Answer 1

Find the area of triangle:

Given,Base is $8\mathrm{cm}$ and height is $3.5\mathrm{cm}$

$$\begin{gathered} =\frac{1}{2}\times \mathrm{B}\times \mathrm{H} \\ =\frac{1}{2}\times 8\times 3.5 \\ =\frac{1}{1}\times 4\times 3.5[\mathrm{Cancel}8\mathrm{by}2] \\ =4\times 3.5=14.0{\mathrm{cm}}^2 \end{gathered}$$

Hence , $14{\mathrm{cm}}^2$is the area of triangle.
