42. 100 meters wide X 50 meters = ?? Pretend Oyster Bed…….. There are 20 oysters per square meter, so how many oysters would be in an area this size? The Great Oyster Sampling….

43. First find the area of the PRETEND OYSTER bed…. 100 meters X 50 meters = 5,000 meters squared Then multiply your SAMPLE SIZE by your AREA SIZE…. 5,000 meters squared X 20 oysters per square meter = 100,000 oysters!!
