Understanding area and perimeter

The Grecian pizza parlour boss brings up from the cellar a box of 80 鈥榮mashing plates鈥� that must be arranged in piles three deep around the perimeter of the restaurant. The guests will smash them at the end of the pizza party after the dancing. Apprentice Ambrose鈥檚 boss explains the difference between area and perimeter. Perimeter is 鈥榯he distance round the outside edge鈥� and area is the 鈥榮pace inside鈥�. Ambrose must work out how many plates he needs and how many boxes to fetch. Ambrose also learns the quick way of finding the perimeter of a rectangle as (2 x length) + ( 2 x width). He measures the restaurant in plates. Three questions of increasing difficulty are asked about area and perimeter based on the pizza parlour scenario.
