A right triangle is a type of triangle that has one angle measuring 90 degrees. The sides of a right triangle are referred to as the base, the height, and the hypotenuse (the longest side opposite the right angle).
Calculation:
The area A of a right triangle can be calculated using the formula:

$\Rightarrow \left(1∕2\right)\times 30\times \mathit{h}=240$
$\Rightarrow \mathit{h}=16\mathit{c}\mathit{m}$
Using the Pythagorean Theorem to calculate hypotenuse
${\mathit{c}}^2={30}^2+{16}^2$
$\Rightarrow {\mathit{c}}^2=900+256$
$\Rightarrow {\mathit{c}}^2=1156$
$\Rightarrow \mathit{c}=34$
Perimeter of the Triangle: The perimeter is the sum of all sides: Perimeter $=$ base + height + hypotenuse.
