# So, I have a math questionApril 19, 2015 12:55 PM   Subscribe

I'm trying to do some online landscape planning but don't have all the information I need. I have problems with simple math. Can y'all help me out?

The hubs and I are closing on a house tomorrow (hopefully), and I want to do some landscaping, I'm trying to get a jump on it by using SketchUp but I have difficulties with math (dyscalculia). So here is a picture of the property lines as given to us by the appraiser (with some information removed to protect the innocent), and as you can see, only a few of the lines actually have measurements on them. Now, I'm sure that there's a simple solution to figuring out the rest of the measurements, but again, I have difficulties with the Maths.

I'd really appreciate if someone could take a look at the picture and just give me the measurements of the lines that don't have them (the ones with the ???). Don't give me the formulas trying to help me help myself... because while I understand math in principle, I honestly make mistakes doing simple math. It's a wonder to behold, just ask my friends and family. ^_^

Here you go.

I used a ruler.

Rather than mathing through it, use the existing measurements as a scale. Assuming you don't have to be incredibly precise, it looks like:

The bottom line is about the same length as the one labeled "160 feet" or 160 feet.
The diagonal one is about 2.5 times the length of the one labeled "160 feet" or 400 feet.

Incidentally, that 182. 4 refers to the length of the property boundary associated with the parcel in the upper right corner. In reality, that chunk of your land looks like about 1.25 lengths of the 80 foot segment, or 100 feet.

Similarly, that bottom 33 is wrong too. Figure 70 feet.

Starting clockwise from the upper left corner, your perimeter is thus approximately (30+80+160+ 100+312+70+160+400) or 1,312 feet.

Are you building a fence? PS: Congratulations!

Overlaid the drawing as closely as I could to a known segment (the 312' length), and had a computer generate the rest. Should be OK to within a foot or two.

Response by poster: Carmicha, we are going to build a fence (we plan on having animals and we don't want them wandering the neighborhood) but I also want to use the satellite images to figure out where, exactly, the existing trees and buildings are in relation to the property lines.

I'm awful with rulers... and Dyscalculia makes me bad with spatial stuff, but SketchUp helps with that a little bit if I have the right numbers...

Thanks, y'all!

If you plan to build a fence, get a real survey by a surveyor licensed in your city/county/state. You will be headed for all kinds of legal trouble if you eyeball those locations.

Your town may require one anyway to get the necessary construction permits. If you're closing on a house tomorrow then a recent one was most certainly generated. You need to get that and not rely on the appraiser's rough sketch.

Response by poster: Yep, we plan on getting an actual survey done too since by all appearances our property line runs through the neighbor's driveway... :-/

But thanks to y'all and the satellite imagery, I have a rough idea of where to put the silly thing and what obstacles are in the way.

Um, not to keep the thread going longer than necessary, but if you may want to be sure there are covenants in place giving your neighbor access to that part of your property so they can use the driveway.

I once owned a house that shared the bottom of the driveway with the adjoining house and we had all kinds of extra paperwork to make sure that everyone was in agreement. Check with your lawyer and make sure none of that is on the county's books.

Web Plot Digitizer could also be used to do this, tutorial here.

Response by poster: Okay, so we signed for this yesterday and it seems that the top part of the property (where it says 20' esmt) is an easement for the road leading to the neighbor's property, so that is where we can build our fence. It looks to be the same length as the line above it but we lose a tiny bit on both sides...

Just thought I'd through this last tidbit out before trying to measure it again on my own... I really do suck at this. Do I just take 20' off both sides?

Working the angles while drawing the map was hard too. :-/ I'm really not good at this math stuff.
