- So basically the gardeners have 36 slabs to make a rest area in the middle of a lawn.
- To make it easy to mow they want the area around the slabs (the perimeter) to be a rectangular shape.
- They want the least space possible around the slabs.
What I have to answer: What arrangement of the tiles gives the smallest possible perimeter? Can you explain why this happens?
Answer: Probably 4 (base) x 8 (height) Or the other way round. Other ways are 10 by 2, 6 be 6 and 1, 11, I think.
Question: If the gardeners had 48 tiles, how would they arrange them?
Answer: 6 (base) x 8 (height). I don't know if this is the answer but I have checked twice and am sure.
Someone has a garden that measures 30 by 20. She wants to fertilise her garden. Each bag covers approximately 200 metres square.
Answer: 3 Bags, because 30 x 20 = 600 and the bags cover 200, so 200 x 3 is 600.
