Calculate the area of a triangle with a base of 12 cm and a height of 4 cm.

To find the area of a triangle, the formula used is:

[

\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}

]

In this question, the base of the triangle is given as 12 cm, and the height is 4 cm. Substituting these values into the formula gives:

[

\text{Area} = \frac{1}{2} \times 12 , \text{cm} \times 4 , \text{cm}

]

Calculating this step-by-step:

1. First multiply the base and height:

[

12 , \text{cm} \times 4 , \text{cm} = 48 , \text{cm}^2

]

2. Now take half of that result:

[

\frac{1}{2} \times 48 , \text{cm}^2 = 24 , \text{cm}^2

]

Thus, the area of the triangle is indeed 24 cm². This calculation confirms the correctness of the selected option, which properly reflects the
