Rosa just finished installing a small koi Pond in her backyard and now needs to re-sod. One side of the koi pond is 2 feet shorter than the other side. One side of the garden is three times the longer side of the koi pond The other side of the garden is 5 feet longer than the first side. How much psi does Rosa need to buy? K
The sketch of the garden and the pond is shown below
Area of garden = length × width Area of garden = [3x + 5] × 3x Area of garden = 3x[3x+5] Area of garden = 9x² + 15x
Area of pond = [x-2] × x Area of pond = x[x-2] Area of pond = x² - 2x
Area to be re-sod = Area of garden - Area of pond Area to be re-sod = 9x² + 15x - [x² - 2x] Area to be re-sod = 9x² - x² + 15x + 2x Area to be re-sod = 8x² + 17x
The amount of sod needed to be bought would depend on how much in each packaging they are being sold.
