Answer:
38.28 cm = D. 38
Step-by-step explanation:
Area of the Rectangle: l x w 
Length: 6 cm 
With: 4 cm
Area = 4 x 6 
Area of Rectangle: 24 cm 
Area of the Triangle: lw(1/2)
Length: 4 cm 
Width: 4 cm 
Area: 4 x 4 = 16 x 1/2 = 8
Area of Triangle: 8 cm
Area of the Circle: pi x r^2 x 1/2
Radius: 2 cm 
Pi: 3.14
Area: 3.14 x 2^2 
Area: 3.14 x 4 = 12.56 
Area of Circle: 12.56 x 1/2 
Lastly, you add them all together: 
24 + 8 + 6.28 = 38.28 cm
 
        
             
        
        
        
0.20a=220
Where 0.20 is the decimal form of 20% 
a is the unknown number
0.20a=220
-------   -----
0.20     0.20
a=1100
220 is 20% of 1100.
