how do u find base times the height?

You multiply the base and the height together.....

To find the area of a triangle when given the base and height, you need to multiply the base length by the height. The base is the length of the bottom side of the triangle, and the height is the length of a perpendicular line drawn from the base to the top vertex of the triangle. Follow these steps to get the answer:

1. Identify the length of the base of the triangle.
2. Identify the length of the height of the triangle.
3. Multiply the length of the base by the length of the height.
4. The result obtained is the area of the triangle.

For example, if the base of a triangle measures 5 units and the corresponding height measures 7 units, the area of the triangle would be 5 units multiplied by 7 units, which equals 35 square units.
