Help me calculate square footage?

08/12/2007 04:58:03 PM · #1

Hello...I came here because I know we have a very wide group of people and some architects and math geniuses, and so on...

Anyway, I need to calculate the square footage of this parking lot:

That is not to scale obviously, but I'm thinking the best way may be to get a ruler with a scale on it, draw it to scale...then make some smaller squares and triangles, etc out of it...I'm lost haha.

--

Also, just to make sure I'm on the right page...

Does 90 square feet = 30 square yards?

Thanks.

PS obviously I'd like to be as close as possible, but if we gotta like triangle off the bottom corner or something, that's fine. But I'd like to be as close as possible.

90 SQ FT = 10 SQ YDs

Also in your picture you have 1 lenght for the bottom lines. There are 2 lines there I need a measurement for the 2 lines

I would divide it into 3 triangles and use the "Area = half x base x perpendicular height" formula to calculate the area. It could be easiest to approximate the bottom left corner as a hard edge instead of a curve.

ok ... can we assume that the bottom line is straight, just cut out that little tip on the bottom.

ok so 90 sq. ft=10 sq. yards...that is why my pricing was so far off when I did it with the two different methods...makes a lot of sense.

If my numbers are correct you are looking at 541,239.244 Sq Ft. Or 60,137.693 Sq Yds.

somewhere less than 4427 sq yards from your diagram, but given you are missing some of the necessary dimensions, its harder to really estimate accurately. (that 2 part bottom line in particular...

I think 4400 sq. yards sounds about right, so around 39,600 sq. feet.

Thanks so much for your help.

What did you do, divide it up into smaller sections and draw it out? Just curious.

You can roughly assume it is a rectangle (well, technically a parallelogram, but rectangle will do) on the right with a triangle butting up against it on the left.

Rectangle is 57'x 359'

Triangle is 359'x(165-57)'x0.5

add them up, divide by 9

Good enough for government work :) It is certainly on the high end, because of the corners I trimmed off/ assumed were there, but should give at least an upper bound to the actual answer.

Sounds good...The total square footage for this property is over 180k...this sounds right.

It is, I was getting ready to eat dinner and though, My number is wrong. I will rethink all this after my stomach is full

35,421 Sq Ft. and 3,935 Sq Yds.
