Answer:
Domain:- All real numbers
Range:-[3,infinite)
Step-by-step explanation:
In the function there's no value of x for which it is not defined thus domain is R.
Now a modulus will have always it's minimum value 0 thus minimum value of function is 0+3=3. And Max value of a modulus is infinite so infinite+3=infinite.
 
        
             
        
        
        
The area is perimeter times height plus area of the bases
        
                    
             
        
        
        
You could do 37+230 or 40 + 235
