Answer:
200 cm^2
Explanation:
Let us start with the formula for the area of a triangle:
In the problem, we are actually given both the base, and the height. Let us plug in these values into the equation above to solve for the area. We have a base of 10 cm, and a height of 40 cm.
Therefore, the area of the triangle is 200 cm^2.
