Question

Elaine is painting a fence. She knows that she needs 1 gallon of paint for each 10 feet of fencing. The fencing will enclose a rectangular yard that is 3 yards long and 2 yards wide. How much paint does Elaine need? (Remember 3 feet = 1 yard)

Answer 1

There are 2 walls that are 9 feet each and then 2 walls that are 6 feet each. Adding those up will give you 30 feet of fencing. If you need 1 gallon for every 10 feet and there are 30 feet of fencing, that would mean that you need 3 gallons of paint.
