Area Estimation for Images with defined edges

The shapes that were measured were that of a circle, triangle, and square. Using scilab and the green's theorem, the following were acquired:
shape - area(pixel count) - Area - percent error
square - 27225 - 26993.5 - 0.850
triangle - 13622 - 13493 - 0.947
circle - 29757 - 29532 - 0.756




I give myself a grade of 8, since the percent errors were minimal but I was helped and guided by Ed David and Jorge Presto.

Activity 1

After counting the number of pixels in each division in the x and y axis, I used ratio and proportion. Using those results I plotted the points of the graph using excel.

I give myself a grade of 9. This is because the graph generated from microsoft excel did not exactly match that of the original image.
