    quadrilateral width

    Is there a way of determining an"average" width for an irregular shape like a quadrilateral? I'm trying to fnd out to determine an "accurate" width for a parcel of land. Thanks.

    I don't think there's a general way: if the irregularity is a "slight one" (and here we already may have problems to agree on what is "slight") then you can take averages: the width in the front side, in the bottom side and one or two in the middle.

    But if your quadrilateral is highly irregular then "average" can be a rather misleading notion.

    Now, what would you like to determine an "average" width for? Is it to determine the quadrilateral's area? If so you can subdivide your quadrilateral in smaller simpler forms, like regular quadrilaterals and/or triangles...

    I totally agree with you that "average" in this case is is somewhat misleading. The quadrilateral/parcel of land is pretty irregular. I'm not looking to determine area. I need to determine an "average" width to determine setbacks for the property. I imagine I almost need some type of computer program or algorithim which could take "millions" of points from width to width & get a more accurate "average". I tried taking the top points, the bottom points and one midway and came up with an average. I then took ten points on each side to side and averaged those and got a more "refined" number. So I guess in the end what I trying to figure out is there a way of using "thousands of point to point measurements" to get an even more refined/accurate "average" in this case scenario. Thanks
