Oil Spill Project

Approaching The Problem

When I first saw the map of the oil spill, I first looked at a certain area and looked for smaller shapes to find the area of. Eventually, I found 21 smaller shapes in Map A. Then I found the area for each one of them.

My Work Done

For each of my bases and heights, I multiplied them by 15 because the scale was 15 mi for 1 cm.

1. 60  x 37.5 /2= 1,125 mi 2

2. 30 x 82.5 = 2,475 mi 2

3. 37.5  x 60 = 2,250 mi 2

4. 30  x 22.5 /2= 337.5 mi 2

5. 37.5 x 75= 277,875 mi 2

6. 22.5 x 30/2= 337.5 mi 2

7. 22.5 x 45/2=506.25 mi 2

8. 22.5 x 22.5= 506.25 mi 2

9. 45 x 97.5= 427.5 mi 2

10. 30 x 22.5=675 mi 2

11. 52.5 x 30/3= 787.5 mi 2

12.  37.5 x 15/2= 281.25 mi 2

13. 60 x 37.5= 2,250 mi 2

14. 82.5 x 45= 3712.5 mi 2

15. 30 x 37.5/2= 562.5 mi 2

16. 82.5 x 45/2= 1856.25 mi 2

17. 3.14 x 22.5 squared=1589.625 mi 2

18. 15 x 30=450 mi 2

19. 3.14 x 15 squared= 706.5 mi 2

20. 22.5 x 15/2=168.75 mi 2

21. 22.5 x 22.5= 506.25 mi 2

Total Area

299,386.125  mi 2

Questions

1. My total is not the same as the actual area because I rounded up on my measuring, whenever there was a measurement close but not quite to a full or half centimeter, I would round it to that full or half centimeter. Plus, it's very hard to get an exact measurement on such a shape because it's so weird looking and harder to make exact smaller shapes.

2. I predict that my measurement of the total area will be slightly larger than the actual area because I often rounded up instead of down.
