Step-by-step explanation:
 base : 30 cm 
height : 20 cm 
perimeter : 27 + 30 + 25 + 10 
                  : 92 cm
Area : (1/2 ( a + b) ) x h
         : (1/2 ( 10 + 30) ) x 20
         : (20) x 20
         : 400 cm
 
        
             
        
        
        
If 3 is x that means y is -17 so that mean f=-17/3
