A rectangular lawn is 120 feet by 60 feet. Tom's lawnmower cuts a path that is 1 foot wide. If Tom started along the outer edge and mowed around the outer edge of the lawn, what fraction of the lawn would he have mowed?
Answer for sheet # 52
Total area of the lawn: 120 feet x 60 feet = 72,00 sq. feet
After cutting 1 foot wide, the inner rectangle is = 118 feet x 58 feet =6844 sq feet
Area Tom cut = 7200 - 6844 = 356 sq. feet
Fraction of the total lawn cut = 356/7200
