Answer:
Base = 8
Step-by-step explanation:
Area of a triangle can be calculated as:
Area = 0.5 x Base x Height
The values of the area and the height are given in order to find the length. 
A= 52 in^2
Height= 13 
First we have to find the base or the length. Using the values above we can set up the equation as: 
1. 52= (0.5)(13)(b)
2. 52/0.5(13)
3. b=8
Answer: The length of the guitar or the base would be 8 inches. 
I hope this helps and for future problems regarding this topic use the formula above!! 
Formula: 0.5 x Base x Height 
 
        
             
        
        
        
Step 1 is wrong it should be: 2x - 3x - 1=3
