Question

The sides of a rectangle are 6.01 meters and 12 meters. Taking the significant figures into account, what is the area of the rectangle?

Answer 1

Don't round down. E: 72.12

Answer 2

Taking significant figures into account, 6.01 has 3 significant figures, and 12 meters has 2. In the rule of multiplication, the answer has to follow the least number of significant figures. This means that the answer we obtain must have only 2 significant figures. To find the area of the rectangle, the two sides are merely multiplied. This is shown below:

6.01 * 12 = 72.12 = 72

Therefore, the area is 72 sq. meters
