The length of the base is 
Step-by-step explanation:
Since we know the formula to find the area of a triangle is
, we can plug in and solve for b. When we plug into the formula we get:
= 
First multiply by 2 on both sides to get rid of the 1/2 on the left. After doing this we get:

Then we can multiply by 5 on both sides to get rid of the 1/5 on the left. After doing this we get out answer:

You can easily take 8*10, since that equals 80, then add +2. Put parentheses around 8*10+2, then multiply that by 3. You should arrive at your answer
The correct answer would be 5/2.
As this is the mixed fraction equivalent.
