Question: What is the length of the altitude from the vertex of a triangle to the base if the area is 40 cm² and the base is 10 cm?

Options:

1. 4 cm
2. 6 cm
3. 8 cm
4. 10 cm

Correct Answer: 6 cm

Solution:

Using the area formula: Area = 1/2 * base * height, we can rearrange to find height: height = (2 * Area) / base = (2 * 40) / 10 = 8 cm.
