` = "Mowing Triangle"`

Enter a value for all fields

The **Mowing Triangle** calculator estimates the distance walked, calories burned and time required to mow an area of grass based on the length of three sides of the triangular area, person's weight, width of mower, mower speed and whether riding or pushing the mower.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**A**) Length of Side A - (
**B**) Length of Side B - (
**C**) Length of Side C - (
**M**) Your Weight (used for calorie calculation) - (
**w**) Width of Mower (cutting swath) - (
**ms**) Mowing Speed (default of 3 mph: human walking average) - (
**RP**) Riding or Push Mower

** Miles Walked Mowing (eM): **The calculator returns the distance traveled while mowing in miles, the area in acres, the time it took in minutes, and the calories burned. However, these can be automatically converted to compatible units via the pull-down menu.

- Humans walk at a rate of approximately 3 miles per hour, ranging from 2.1 for women over 80 to 3.2 for men in their 30's
- 4 miles per hour (mph) is considered a good speed for a riding mower. 5.5 mph is considered very fast with an upper limit of 7 miles per hour.
- Most push mowers cut 21" wide swaths.
- Riding mower range from 36" to 54" for larger zero turn mowers.

According to a report from Valdosta University, the following calories per hour are associated with mowing (cutting) grass. These are approximate numbers based on the person's weight, and there are numerous other factors that can change the total calories burned.

Very few yards are perfect rectangles. In order to estimate the distance walked while mowing, one must first estimate the total mowing area. This calculator uses the width of the swath created by the mower to then compute the linear distance walked. Most push mowers are between 18" and 24" wide. This calculator assumes that there is an overlap of two inches (2") when mowing rows.

It also provides the oval area and perimeter.

**Straw Cover Area Calculator**: Computes the number of regular square-bales of straw needed to cover an area such as a field or garden for new grass seed. The common bales are 2 string square bales of 14"x18"x"36" inches weighing between 40lbs and 60 lbs.**Bales of Straw over Rectangle:**compute the number of regular square-bales of straw needed to cover new seed on a rectangle area (length by width). .**Market Price for Bales of Straw**: Returns recent market survey on the price of straw bales.

**Three Sided Land Size**: Computes the square feet, acres and perimeter in land with three straight sides.**Four Sided Land Size (squared)**: Computes the area in square feet and acres and perimeter in feet of rectangle land with roughly squared corners based on the length and width.**Four Sided Land Size (not squared)**: Computes the area and perimeter of four sided land based on side lengths and a length of a diagonal.**Five Sided Land Size**: Computes the area and perimeter of a five sided land based on side lengths and the lengths of two diagonals.**Circular Land Size**: Computes the area of land in roughly circular shape based on the width (diameter).**Simi-Circular Land Size**: Computes the area of land in roughly semi-circular shape based on the width (diameter).**Oval Shaped Land Size**: Computes the area of land in roughly an oval (ellipse) shape based on the length and width.**Human Paces to Feet and Meters**: Estimates a length (feet, yards and meters) based on the number of paces a person takes to walk it and the approximate length of stride.

For large areas (lawns, gardens or fields), it may be hard to measure longer lengths, because you have no measuring device to make the long measurements (electronic device or long measuring tape or twine). In this case, an estimate can be achieved by using paces (your steps).

To estimate a length with paces, you first have to make a reasonable estimate 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.

Often it is required to put land pieces together to compute to total area of land. The land shown can be accurately computed by individual triangles. The area of 5 sided land function requires the diagonals that create three triangles that are summed to compute the area in a 5 sided piece of land.
