The diagram shows the length and width of a cell phone, and the length of a larger version of the same brand cell phone.

The lengths and widths of the two cell phones are proportional. What is the width, in inches?

\qquad \qquad \bf \huge\star \: \: \large{ \underline{Answer} } \huge \: \: \star

  • missing length = 2.99 in


\textsf{ \underline{\underline{Steps to solve the problem} }:}

Both the figures are similar to each other, so ratio of their corresponding sides will be equal to one another.


\qquad❖ \: \sf \: (2.6)/(5.4) = (x)/(6.21)

( taking missing width be x )


\qquad❖ \: \sf \: x = (1.3)/(2.7) \sdot6.21


\qquad❖ \: \sf \: x = {(1.3)}{} \sdot(2.3)


\qquad❖ \: \sf \:x = 2.99 \: \: in


\qquad \large \sf {Conclusion} :

Missing side measures : 2.99 inches
