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 calculated using the formula:

\[A = \frac{1}{2} \times \text{base} \times \text{height}\]


Step 2: Substitute the given values
Given values are:
- Base = 12 cm
- Height = 5 cm

Substitute these 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:
The triangle's area is \( 30 \, \text{cm}^2 \). Therefore, option (1) is correct.
