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

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 solve for height: 40 = 1/2 * 10 * height, so height = 8 cm.
