Question

Find the area of a triangle with base 12 cm and height 5 cm.

• A. \( 30 \, \text{cm}^2 \)
• B. \( 60 \, \text{cm}^2 \)
• C. \( 24 \, \text{cm}^2 \)
• D. \( 15 \, \text{cm}^2 \)

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: Recall the formula for the area of a triangle
The area \( A \) of a triangle is given by the formula: \[ A = \frac{1}{2} \times \text{base} \times \text{height} \]
Step 2: Substitute the given values
We are given: - Base = 12 cm - Height = 5 cm Substitute these values into the formula: \[ A = \frac{1}{2} \times 12 \times 5 \]
Step 3: Simplify the expression
\[ A = \frac{1}{2} \times 60 = 30 \, \text{cm}^2 \]
Answer:
Therefore, the area of the triangle is \( 30 \, \text{cm}^2 \). So, the correct answer is option (1).
