Answer:
200 cm^2
Explanation:
Let us start with the formula for the area of a triangle:
![\triangle Area=(base\ *\ height )/(2)](https://img.qammunity.org/2022/formulas/mathematics/college/edskzsdztk79qiawbg270ymq41dam36efg.png)
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.
![\triangle Area= (10*40)/(2) \\\triangle Area= (400)/(2) \\\triangle Area= 200](https://img.qammunity.org/2022/formulas/mathematics/college/j008er7zdfud5zf4hqndtv8ze0np0qal3q.png)
Therefore, the area of the triangle is 200 cm^2.
