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. what was the area of the canvas which was covered by the red rose?

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
 
 the area of the canvas which was covered by the red rose was:
 x = 370 in ^ 2
