Question: 1 / 400

What is the area of a triangle with a base of 12 cm and height of 5 cm?

20 cm²

24 cm²

30 cm²

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 12 cm, and the height is 5 cm. Plugging in these values into the formula gives:

\text{Area} = \frac{1}{2} \times 12 \, \text{cm} \times 5 \, \text{cm}

Calculating this step-by-step:

1. First, multiply the base by the height:

12 \, \text{cm} \times 5 \, \text{cm} = 60 \, \text{cm}^2

2. Then, multiply by $ \frac{1}{2} $:

\frac{1}{2} \times 60 \, \text{cm}^2 = 30 \, \text{cm}^2

Therefore, the area of the triangle is 30 cm². This confirms that the correct choice reflects
