Question

The sides of a rectangle are 6.01 m and 12 m. Taking the significant figures into account, the area of the rectangle is *
​

Answer 1

Answer:

Area = 6.01 × 12 = 72.12

As per significant figure rules the answer is 72 m2 because the least significant figures in the case of sides is 2

Explanation:

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
