A triangle has corners at (0, 0), (8, 0) and (3, 6). What is its area?
Answer and explanation
Correct answer: D. 24 square units
- Step 1: Take the side from (0, 0) to (8, 0) as the base: length 8. Step 2. The height is the vertical distance of (3, 6) from the base: 6. Step 3. Area = 1/2 × 8 × 6 = 24. Answer: 24 square units. Why not the others: 48 square units: This forgets to halve base × height. 18 square units: This uses 3 as the base and 6 as the height. 14 square units: This adds the base and the height.
