Vedclass · Answer

(D) The formula for the area of a rectangle is $	ext{Area} = 	ext{length} 	imes 	ext{breadth}$.Given,$	ext{length} = 3.124\,m$ and $	ext{breadth} = 3.002\,m$.Calculating the product: $3.124 	imes 3.002 = 9.378248\,m^2$.According to the rules of significant figures,the result of multiplication should have the same number of significant figures as the measurement with the least number of significant figures.Here,both $3.124$ and $3.002$ have $4$ significant figures.Therefore,the final result should be rounded to $4$ significant figures.Rounding $9.378248$ to $4$ significant figures gives $9.378\,m^2$.
