Q3. lam going to build a vegetable patch in my garden. Thave decided to make the garden bed 4 m eters long and half as wide. a) Draw a scaled diagram of the patch below and calculate the perimeter. Scale Diagram: Perimeter: b) Idonotlike the sharp edges ofmyvegetable patchsolhave decided to round offeitherendwith asemi- circle, so thatitlooks like the diagram below. Calculate the perimeterofthe garden bed now.Show your working out. 4m c) Ifgarden edging costs $3.79 permeterandIcanonly buyitin fullmeters (ig, roundup to thenext meter) how much will it cost me to edge the vegetable patch? Show yourworking d) Inow need to dig outthe old soil to a depth of 200mm. Calculate the volume ofsoillhave to remove. Show your working out. e) lam going to line this space with weed matting, calculate the surface area of my excavated vegetable patch. Show your working out. f) Finally, Iwillbackfillm ygarden with a mix ofcomposted soiland the excavated soil. Iwilluse a ratio of three parts composted soilto one partexcavated soil.

Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
