Brinn's rectangular kitchen has an area of 81 square feet. The kitchen is 9 times as many square feet as Brinn's pantry. If the
rectangular pantry is 3 feet wide, what is the length of the pantry?
1 answer:
Divide 81 by 9 to get the area of the pantry which is 9 so the other side of the pantry is 3 because 3 times 3 is 9.
