Oil Spill Project- By: Emily Green

To find the total area of the oil spill on Map A, I had to split the map up into different squares, triangles, and rectangles. To get the area of the shapes you have to measure two of the sides with the cm side of the ruler then multiply those numbers by 15( 1 cm = 15 mi). After the numbers were multiplied by 15 I multiplied those numbers together to get the final area of the shape. Example: 3 x 15= 45, 2 x 15= 30, 45 x 30= 1,350 miles. To get the area of the triangles we do the same thing but dived by two. Example: 3 x 15= 45, 1.5 x 15= 22.5, 22.5 x 45= 1,012 / 2= 506.25 miles. Once I did this with every shape I added all of the areas together to get the total area of the oil spill on the map. The area was 28,610.19 miles squared. I think that my area is the exact same measure because in the numbers there was lots of decimals and some of them we rounded and some we did not. But I also think that the area I came to is not far off from the exact measure. I believe that my polygons are not going to be exactly the measurement they would be in the actual oil spill. I think this because a lot of the shapes have round corners but I measured them as straight and a full rectangle, square, or triangle. So, they would most-likely be over the measurement.
