Answer:
15
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
Using the given information,
45 = 1/2 * L * 6
45 = 3L                                simplify
15 = L                                   divide both sides by 3
 
        
             
        
        
        
in decimal form it is 45.2
in exact form it is 32 squareroot 2
 
        
             
        
        
        
The number in brackets represents the percentage change
