Question

If the height and base of the right triangle is 12 cm and 9 cm resp., the area of the triangle is __ $c{m}^2$.

Answer 1

For a right angled triangle, the area of the triangle = $\frac{1}{2}\times height\times base$

Therefore, the area of the triangle = $\frac{1}{2}\times 12\times 9$ = 54 $c{m}^2$

Therefore the area of the triangle is54 $c{m}^2$
