Helping the Gardeners at Kew Gardens, London. 3.MD.8 Day 10

Materials Per Group or Pair: Task 1 and 2 Per Student: Task 3 Exit Ticket

Warm Up! Name the polygon. If it is a regular polygon and one side is 15 m long, find the perimeter. Can you write more than one expression to solve the problem?

Kew Gardens in London is a famous botanical garden. There are many borders containing flowers and shrubs in the shape of many different polygons. There are many reasons for the gardeners to know about perimeter!

Question: How do mathematicians and gardeners find the perimeter of their borders? KnowDo area perimeter find perimeter

Task 1: Rose Border. 3m 5m 3m 4m 3m 6m Part A: How much border material is needed? Part B: If border costs $4 per meter, how much will it cost to put border in? 8m The rose gardeners are placing border material around the rose border shown in the diagram

Task 2: Vegetable Border Over in the vegetable garden, gardeners are preparing to install a small fence to keep rabbits out. They purchased 68 yards of fence. The long sides of the garden each measure 9 yards. The short sides are all congruent. How much fence is needed for each short side?

Task 3: The Patio A new patio is being built outside the café. The architects want the edges of the patio to be edged with bushes. Part A: How much of the patio edge will be lined with bushes? Part B: If each meter of boxwoods contains 2 bushes and if each bush costs $8, what will the cost be? 7m8m 15m 10m

Question: How do mathematicians and gardeners find the perimeter of their borders? KnowDo area perimeter find perimeter

Task 3: Art Show EXIT TICKET: The annual flower bed is shown below. What is the perimeter? 11 feet 7 feet 15 feet 3 feet
