I added some labels to the diagram so that I can refer to it. I need to find the lengths of BD and DA and this is where I need to assume that the drawing is approximately to scale. I printed the diagram after turning off any scaling on my printer. I then measured the lengths of AB, CD and DE in Centimeters as accurately as I could. Her is what I found.
These three scale factors should be the same. They are not but they are close so I found their average, 18.22 ft/cm and used it as a scale factor in order to approximate the lengths I need. I next measured the lengths of BD and DA in centimeters on the diagram and multiplied each by 18.22 to approximate the lengths on your lot. I found the length of DB to be 167.59 feet and the length of DA to be 107.47 feet. I then saw the lot as the quadrilateral ABCD and the triangle ADE. The area of the quadrilateral I found using the tool that Steve wrote. The calculated area is 14214 square feet. I then calculated the area of the triangle ADE using Heron's formula and found it to be 825 square feet. Thus my approximation of the area of your lot is 14214 + 825 = 15039 square feet. Harley
