(C) The area of one square is given as $a = 5.29\ cm^2$.The total area $A$ of $7$ such squares is calculated as $A = 7 	imes a$.Substituting the value,$A = 7 	imes 5.29 = 37.03\ cm^2$.According to the rules of significant figures,when multiplying a measured value by an exact number (like $7$),the result should have the same number of significant figures as the measured value.The value $5.29$ has $3$ significant figures.Therefore,the final result $37.03$ must be rounded off to $3$ significant figures.Rounding $37.03$ to $3$ significant figures gives $37.0\ cm^2$.

The area of a square is $5.29\ cm^2$. The area of $7$ such squares taking into account the significant figures is ........... $cm^2$.
