*Aerical Picture B of the Old Spill*

**1) ****Rectangle**

**2.5 cm x 15 m = 37.5 m**

**7 cm x 15 m = 105 m**

**37.5 m + 105 m = 142.5 m****2**

**2) Rectangle**

**3 cm x 15 m = 45 m**

**2.9 cm x 15 m = 43.5 m**

**45 m + 43.5 m = 88.5 m2**

**3) Triangle**

**2.5 cm x 15 m = 37.5 m**

**4.9 cm x 15 m = 73.5 m**

**37.5 m + 73.5 m = 111 m**

**111 m / 2 = 55.5 m2**

**4) Rectangle**

**7.4 cm x 15 m = 111 m**

**2.2 cm x 15 m = 33 m**

**111 m + 33 m = 144 m2**

**5) Triangle**

**2.2 cm x 15 m = 33 m**

**3.5 cm x 15 m = 52.5 m**

**33 m + 52.5 m = 85.5 m**

**85.5 m / 2 = 42.75 m2**

**6) Rectangle**

**3.5 cm x 15 m = 52.5 m**

**3.2 cm x 15 m = 48 m**

**52.5 m + 48 m = 100.5 m2**

**7) Rectangle**

**1 cm 15 m = 15 m**

**3.5 cm x 15 m = 52.5 m**

**15 m + 52.5 m = 64.5 m2**

**8) Triangle**

**3.5 cm x 15 m = 52.5 m**

**3 cm x 15 m = 45 m**

**52.5 m + 45 m = 97.5 m**

**97.5 m / 2 = 48.75 m2**

**9) Triangle**

**2.5 cm x 15 m = 35.5 m**

**3 cm x 15 m = 45 m**

**35.5 m + 45 m = 80.5 m**

**80.5 m / 2 = 40.25 m2**

**10) Rectangle**

**4.5 cm x 15 m = 67.5 m**

**2 cm x 15 m = 30 m**

**67.5 m + 30 m = 97.5 m2**

**Total**

**142.5 m2 + 88.5 m2 + 55.5 m2 + 144 m2 + 42.75 m2 + 100.5 m2 + 64.5 m2 + 48.75 m2 + 40.25 m2 + ****97.5 m2 = 824.74 m2**

*Taking a second look at your sectioned polygons from your map, do you think your area is an exact measure of the space affected by the spill?*

*I do think all of my areas is exact same. I think this because I measured all each shape by length and width. Then I Multiplied length x 15 miles for all of the shapes and do the same to Width x 15 miles for all of the shapes. If you have a triangle shape you in to do length x 15 miles and width x 15 miles, then you add them up to get the total, and then you divide the total divide by 2, and finally you get your answer of the triangle. This is why I do think all of my areas is exact same.*

*How accurate do you think your polygons compare to the actual spill area? Do you expect your answer to be more or less than the actual spill area?*

**I thought it would be less than the actual spill area. I thought its was less because I have less shape. Also I thought its was less by its looks on the Oil Spill Maps.**
