angel is carpeting a rectangular conference room that measures 20 feet by 30 feet. If carpet comes in rectangular pieces that measures 5 feet by 4 feet, how many pieces will she need to carpet the entire room?
First multiply 20 by 30 to get the area of the floor. 20 times 30 is 600. Now multiply 5 by 4 to get 20. to see how many pieces she needs do 600 divided by 20. (600 divided by the size of the rectangles) The answer is 30. She will need 30 rectangle pieces :)
