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 is given as 10 cm and the height is given as 5 cm. Plugging these values into the formula:

[ \text{Area} = \frac{1}{2} \times 10 , \text{cm} \times 5 , \text{cm} ] [ \text{Area} = \frac{1}{2} \times 50 , \text{cm}^2 ] [ \text{Area} = 25 , \text{cm}^2 ]

Therefore, the area of the triangle is 25 cm². This is why the correct answer reflects that. The calculation demonstrates that with the specified measurements of the base and height, the resulting area indeed amounts to 25 cm².
