How many feet of fence does Alice need to plant bushes around? ** First find the total distance the bushes need to cover: 16 feet/side * 3 sides = <<16*3=48>>48 feet
How many bushes does Alice need to buy? ** Then divide the total distance to fill by the distance each bush fills to find the number of bushes Alice needs to buy: 48 feet / 4 feet/bush = <<48/4=12>>12 bushes
