  • missing length = 2.99 in

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

[tex] \qquad❖ \: \sf \: \dfrac{2.6}{5.4} = \dfrac{x}{6.21} [/tex]

( taking missing width be x )

[tex] \qquad❖ \: \sf \: x = \dfrac{1.3}{2.7} \sdot6.21[/tex]

[tex] \qquad❖ \: \sf \: x = {(1.3)}{} \sdot(2.3)[/tex]

[tex] \qquad❖ \: \sf \:x = 2.99 \: \: in[/tex]

Missing side measures : 2.99 inches
