Crude oil released from the well washed up on approximately 1,313 miles of coastline around the Gulf of Mexico. The total length of the coastline of the Gulf of Mexico is approximately 3,540 miles. Calculate the percentage of the coastline along the Gulf of Mexico that was directly affected by the Deepwater Horizon oil spill.

The percentage of the coastline along the Gulf of Mexico that was directly affected by the Deepwater Horizon oil spill is 37%

The percentage of the coastline affected can be obtained as follow:

Percentage = (coastline affected / total) × 100

Percentage = (1313 / 3540) × 100

Percentage = 37%
