GOLD:

1. I have 2 square shaped allotments. Allotment one is 8m long and allotment two is 12m long. a. What is the perimeter of each allotment? b. What is the difference in perimeter of the allotments?

2. I am going to build a wooden fence around allotment two. It cost £8 per metre of wood. How much would it cost to buy the wood for the whole fence?

3. The wood goes on sale and is reduced to £5 per metre. a. How much will it cost if I buy it now? b. How much money will I save?

PLATINUM:

Drawings of different sized allotments have been given to a gardener.  He needs to know which allotment will fit the type of tree. 

Can you help him by calculating the perimeter of each enclosure?

Which enclosure would be suited for which plants?
