Answer:
8 (units)
Step-by-step explanation:
The formula to find the area of a triangle is A = 1/2(b*h). Since we know the area already, we can substitute that value in to calculate the answer backwards. 
Plug in the numbers known:
A = 100
h = 25
Equation: 100 = 1/2(b*25)
Now solve:
100 = 1/2(b*25)
200 = b * 25
<em>8 = b</em>
So, the answer to your question is 8 (units). 
Hope this helps!
