The area of a right-angled triangle with hypotenuse 17 cm and one side being 8 cm shall be:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $60\, cm^2$
Given a right-angled triangle:
- Hypotenuse = 17 cm
- One side = 8 cm
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:
$\text{Area} = \frac{1}{2} \times 8 \times 15 = 60 \text{ cm}^2$
