Kendra has a painting canvas that is 20 inches wide by 37 inches high. She painted a red rose, which covered 50% of the canvas.
uysha [10]
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
