The length and breath of a metal sheet are 3.124 m and 3.002 m respectively. The area of this sheet upto four correct significant figure is :
Options
A.9.378 m2
B.9.37 m2
C.9.378248 m2
D.9.3782 m2
Solution
Area of metal sheet = 3.124 × 3.002 = 9.378248
Now, the result must have significant figures equal to the least of figure being multiplied, so Area of mental sheet = 9.378 m2
Now, the result must have significant figures equal to the least of figure being multiplied, so Area of mental sheet = 9.378 m2
