Answer: 45 is 75 percent of 60
Step-by-step explanation:
 
        
             
        
        
        
The total area is:
 A = (20) * (37)
 A = 740 in ^ 2
 We can make the following rule of three:
 740in ^ 2 -----> 100%
 x --------------> 50%
 Clearing x we have:
 x = (50/100) * (740)
 x = 370 in ^ 2
 Answer:
 the area of the canvas which was covered by the red rose was:
 x = 370 in ^ 2
        
             
        
        
        
Your proportion should look something like this

After cross multiplication, you should end up with this equation

After dividing 4 on both sides, you should get that x=9
