Enter a value for all fields

The **Size of a Garden** calculator computes the area of a patch of land with four straight sides (a quadrilateral) given the length of the four sides and the length of a diagonal between opposing corners. * four sided garden or field *

**INSTRUCTIONS**: Start in one corner of your garden, and measure the length of the four sides (a,b,c,d). Then from the original corner, measure the diagonal (D) to the far corner. See diagram. Use the measurements and enter the following:

- (a) - length of side a
- (b) - length of side b
- (c) - length of side c
- (d) - length of side d
- (D) - the length of the diagonal (See Diagram)

The **Area (A)** is computed in square feet (ft^{2}). However, the calculator allows the user to choose different units (e.g. yards, meters, miles) and the calculator accounts for the different units in computing the area. Furthermore, the output units can also be automatically converted to square meters and many more units via the pull down menu next to the answer.

For large measurements, it may be hard to accurately measure the length of the garden or field because you have no measuring device to make the long measurements. In this case, an estimate can be achieved by using paces. To do this you first have to make a good estimate of measurement of a regular pace while in stride. To do this, put a mark on the ground, and step back several paces. Start walking to the mark, and start counting some number of paces past the mark (e.g. 10). A that point, stop and measure the length. For example a man of six feet tall with a normal stride walked 14 paces in 40 feet. That gave him a feet per pace of 2.857 feet per pace. To compute the Feet per Pace, CLICK HERE. You can then walk off the measurements, using a steady pace, and convert the Paces to Feet by CLICKING HERE. It's a rough estimation method, but not without it's uses.
