Draw any shape you want on a piece of paper. No matter if it’s a circle, rectangle, or a polygon. Now imagine you are an ant and have been made to walk the entire distance around this shape starting and stopping at the same spot. Guess what? That’s perimeter! Simply put, perimeter is the total distance around any 2D shape. If you know the various lengths of each side, you can add them together. For a circle, the perimeter is called circumference and is computed by multiplying, 2 x pi (3.14…) x the radius (half of the diameter). Even cooler is the notion that the perimeter or circumference is what bounds space inside a shape, known as Area.Remember coloring…staying inside the lines? That’s sort of what calculating an “area” is all about. For a four-sided figure, it’s length x width. For a circle, it’s pi x the diameter. Students have these formulas down sometime around middle school. However, teachers get them started as early as first grade these days, using area and perimeter word problems, games, and worksheets as their tools of the trade. 2D Shapes Area and Perimeter Calculator: It is a powerful calculator which calculates area, perimeter and the centroid of 20 regular 2 dimensional shapes as listed below. Also performs the reverse calculation i.e. if area is known find the other parameters. Geometry Volume and Area: Find the formula to calculate Volume, Area, Perimeter & Surface Area for Geometric shapes like square, triangle, circle, cone, cylinder, sphere etc. Learn Area and Perimeter: Learn Area and Perimeter allows users to learn the relationship between area and perimeter. Users can draw any shape on the provided grid and the area and perimeter will be calculated when the shape is enclosed. Deed Calls – Area – Perimeter: “Deed Calls – Area – Perimeter” is a handy universal app for iPAD, iPhone and iPod touch that lets you easily convert real property description into a boundary map. Find Length and Area on Map: Measure any Area or Distance on the map with highest Accuracy.Find area, length,distance on the map.Provide accurate resultsHow To use:select map modeSet the units from settingsZoom to the location you want to measureTap along the outline where you want to measureApp will shows the length/area of the selected location.
