Question

Alex is building a fence around his vegetable garden which is in the shape of rectangle with length of 30 feet and width of 40 feet. Alex completed the fencing in 12 hours. What is the unit rate at which Alex put a fence around his vegetable garden?

Answer 1

It's a bit of a trick question lemme break it down. it's asking for perimeter since it's in a shape of a rectangle. sl 30+30+40+40=140 ft of fencing. he completed it in 12 hours so 140/12=11.6 ft of fencing/hr!
