How do you measure a rectangular land with 4 different dimensions?

Answer 1

If there are 4 different dimensions to a rectangular land, post in on FB...and tell your local news...I have only seen a 2 dimensional land (even normal objects have only 3 dimensions).

Now to get serious [if you are that serious ignore all the [] like this, but do look out for ()]. If you mean coordinates, it isn't hard either. After all, you already said it is rectangle. Find the length of 2 adjacent sides [touching each other on one point] and multiply them together to get the area [if you want to measure just take a measuring tape and go to the points to do it].

If it isn't rectangular but just 4 sided, arrange the points in this formula (if you dont understand it, wikipedia has the possibly clearer explanation, search for "shoelace formula")

x1 x2 x3 x4 x1

y1 y2 y3 y4 y1

where the coordinates of the points are (x1,y1) (x2,y2) (x3,y3) (x4,y4) linked to the previous point by a single line. From now it might get confusing so good luck

(x1 * y2) + (x2 * y3) + (x3 * y4) + (x4 * y1) - (y1 * x2) - (y2 * x3) - (y3 * x4) - (y4 * x1)

Remove the negative (if there is) and divide the result by 2. You will get the answer
