A triangle has sides 6, 8 and 10. What is its area?
Answer and explanation
Correct answer: A. 24
- Step 1: 6^2 + 8^2 = 100 = 10^2, so the triangle is right-angled with legs 6 and 8. Step 2. Area = (6 x 8)/2 = 24. Answer: 24. Why not the others: The hypotenuse cannot be used as a height, and the product of legs must be halved.
