The area of a right-angled triangle with hypotenuse 17 cm and one side being 8 cm shall be: |
$68\, cm^2$ $60\, cm^2$ $120\, cm^2$ $136\, cm^2$ |
$60\, cm^2$ |
The correct answer is Option (2) → $60\, cm^2$ Given a right-angled triangle:
First, find the other side using Pythagoras theorem: $\text{Other side} = \sqrt{17^2 - 8^2} = \sqrt{289 - 64} = \sqrt{225} = 15 \text{ cm}$ Now calculate the area: $\text{Area} = \frac{1}{2} \times 8 \times 15 = 60 \text{ cm}^2$ |
