Question

What is the area of a triangle with base \( 12 \, \text{cm} \) and height \( 8 \, \text{cm} \)?

• A. \( 48 \, \text{cm}^2 \)
• B. \( 60 \, \text{cm}^2 \)
• C. \( 40 \, \text{cm}^2 \)
• D. \( 36 \, \text{cm}^2 \)

Hint:

Remember: The area of a triangle is calculated using \( A = \frac{1}{2} \times \text{base} \times \text{height} \).

Answer 1

The Correct Option is A

Step 1: Use the formula for the area of a triangle
The area \( A \) of a triangle is given by: \[ A = \frac{1}{2} \times \text{base} \times \text{height} \] Step 2: Substitute the given values
Given:
- Base = \( 12 \, \text{cm} \),
- Height = \( 8 \, \text{cm} \).
Substitute these values into the formula: \[ A = \frac{1}{2} \times 12 \times 8 = \frac{1}{2} \times 96 = 48 \, \text{cm}^2 \] Answer: Therefore, the area of the triangle is \( 48 \, \text{cm}^2 \). So, the correct answer is option (1).
