Corinne’s new dog pen is a rectangular pen that measures 12 yards by 4 yards. She reduced the area of her old rectangular dog pen by 60% after adopting out 6 puppies. List some possible dimensions of Corinne’s old dog pen. Explain your reasoning.
The current area is 12x4 which is 48yards^2. 60 percent of that is 48x0.4=19.2. Now you can just put some random numbers that when multiplied = 19.2. For ex. 2 and 9.6, 4 and 4.8.
