Anthony Chen's family operates a full-service pool and landscaping business. Sometimes their clients want low decorative fences around their flower beds.

Anthony's father wants a quick way to estimate the amount of fencing needed. Mr. Chen asked Anthony to help him. Anthony

realizes that this is just a perimeter question.

He starts his task by analyzing the relationship between the length of the side of a square flower bed and the perimeter of the

flower bed. This will tell him the amount of fence needed to enclose the flower bed. Anthony realizes that lengths of sides of

flower beds are not always whole numbers, but he decides to use square tiles to build models of flower beds of various sizes to

help him find a pattern. In his models, 1 tile represents 1 square foot.
