Answer:
The area of a triangle can be calculated using the formula A = 1/2 * b * h, where A is the area, b is the base of the triangle, and h is the height of the triangle.
In this case, we know that the area of the triangle is 30 and the height is 10. Substituting these values into the formula, we get:
30 = 1/2 * b * 10
Simplifying, we get:
b = 2 * 30 / 10 = 6
Therefore, the base of the triangle is 6 units.
