Answer:
8 meters
Explanation:
The formula for the area of the triangle is 
. You can do inverse operations to find the length. 
You can solve this question algebraically.
24 = 

Multiply both sides by two to isolate the variable. 
48 = l · 6
Divide both sides by 6. 
 = 8
l = 8
So, the length of the triangle is 8 meters.
