What is the area of a triangle with a base of 8 and a height of 5?

• A. 20
• B. 30
• C. 40
• D. 50

Answer: (A)

To find the area of a triangle, you can use the formula: \[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \] In this case, the base of the triangle is 8 units and the height is 5 units. Substituting these values into the formula gives: \[ \text{Area} = \frac{1}{2} \times 8 \times 5 \] \[ \text{Area} = \frac{1}{2} \times 40 \] \[ \text{Area} = 20 \] Thus, the area of the triangle is 20 square units, which confirms that the correct answer is indeed 20. Understanding this formula is crucial as it applies to any triangle, making it a fundamental concept in geometry.
