There are 43,560 square feet in a acre; this is 4,840 square yards. You can find a conversion calculator at http://www.unitconversion.org/area/acres-to-square-foots-conversion.html If the land is a perfect square, it is 208.71 feet wide by 208.71 feet long. Originally, the size of an acre was approximately the amount of land an ox could plow in a day. Today, the easiest visualization might be the sideline to sideline area of 90.75 yards of a standard american football field. Lot sizes are commonly measured in acres or a fraction thereof. A typical suburban residential lot would measure 0.15 - 0.50 acres. As you move to more rural areas 5, 10, 20, 40, and 80 acre parcels are very common.
If the land is rectangular in shape, you would have to know at least the length of one dimension in order to figure the other.
Dave,
great points to know...i can use them...i like the ox could plow and football one!
Great tips to have I know sometimes we often forget the basics of math. Thanks for sharing this information.
I've got an app on my iphone that does this for me. There really is an app for everything. LOL
interesting information, about the OX I mean. I had no clue where this came from.
Ooooh, oooooh!!! I know this! I took (and passed) my broker's test this past spring. Although they didn't ask me this, I had it memorized and ready to go....just in case.
Hi Dave,
I'd like to add one thing to your blog. A builders acre is 40,000 sq ft. Thats a term we use often in my neck of the woods.
Regards,
Roy
