Saving water by converting a lawn to a water efficient garden We are still in a drought, and still need to conserve water. One of the most effective ways to conserve water is to convert a lawn into a water efficient garden. By doing so, not only will you save water, you might also be eligible for receiving rebate(s) from various rebate programs offered by water agencies or cities you live in. Find out the size of your garden The first step of any garden planning is to find out its size. Here is a simple guide. 1. Find out the yard’s shape Most yards are of the shape of rectangle, triangle, circle or semi-circle, or a combination of these shapes. If the shape is a combination, break them into separate shapes. 2. Determine which measurements are required for the calculation, and obtain them. For example, length and width are required for a rectangle. 3. Do the calculation. Below are some sample garden shapes and how the sizes can be calculated. a. Size = a*b b. Size = (a*b)/2 c. Size = (a*b) + (a*c) /2 Actual Examples Here are some actual examples. This yard basically can be considered as a rectangle. The measurements can be obtained along its long and wide borders, then the size can be calculated. This yard can be broken into a rectangle and a semi-circle. It can be calculated using the formula in d) above. A fun math project If you have teens at home who just studied their geometry, this can be the perfect opportunity for them to apply what they learned! After you determine the shape, take the measurements, and apply the formulas, you can easily find out the size of your yard. With the size known, you can proceed to the next step of the planning for a water efficient garden.
