The picture in the attached figure
let 
AB=x
we know that
perimeter of the figure=10*x
perimeter=42.5 cm
so
42.5=10*x
x=42.5/10
x=4.25 cm
area of the figure=area of rectangle +area of square
area of rectangle=4.25*(4.25*3)----> 54.1875 cm²
area of square=4.25²----> 18.0625 cm²
area of the figure=54.1875+18.0625-----> 72.25 cm²
the answer is72.25 cm²
 
        
        
        
Answer:
3600
Step-by-step explanation:
0.1*4000=400
4000-400=3600 gallons
 
        
             
        
        
        
that question doesnt make sense!
 
        
             
        
        
        
1/5 is greater because it equals 0.2
0.2 has an imaginary 0 at the end, to make it 0.20
.20 > 0.15
Therefore, 1/5 is greater than 0.15
