Find the area of a right triangle whose two legs are 9 cm and 12 cm.

Step-by-step solution

1. Area of a right triangle is $\frac{1}{2}\times \text{base}\times \text{height}$.
2. Take the legs 9 cm and 12 cm as base and height: $\frac{1}{2}\times 9\times 12=\frac{1}{2}\times 108=54$.
3. Thus the area is $54$ square centimetres.
