Question

How do you work out the length of a triangle$?$

Answer 1

Finding the length of the triangle:

We can find the length or height of the triangle by using the formula of area of the triangle.

Which is given as: $\mathit{A}\mathbf{}\mathbf{=}\mathbf{}\frac{\mathbf{1}}{\mathbf{2}}\mathbf{\times }\mathit{B}\mathbf{\times }\mathit{H}$

Where, $A$ is the area of triangle

$B$ is the base of the triangle

and $H$ is the height of the triangle

Now, height of the triangle will be $H=2\times \frac{\mathrm{A}}{\mathrm{B}}$

Hence, we can find out the length/height of the triangle by the formula $\mathit{H}\mathbf{}\mathbf{=}\mathbf{}\mathbf{2}\mathbf{\times }\frac{\mathbf{A}}{\mathbf{B}}$.
