Answer:
A. [tex]7.7[/tex]
Step-by-step explanation:
First Rectangle
[tex]L=11cm[/tex]
[tex]W=10cm[/tex]
Second Rectangle
[tex]l=?[/tex]
[tex]w=7cm[/tex]
Since the two rectangles are similar the corresponding sides are in the same proportion;
[tex]\frac{l}{L}=\frac{w}{W}[/tex]
Substitute the values to get;
[tex]\frac{l}{11}=\frac{7}{10}[/tex]
Multiply both sides by 11;
[tex]l=\frac{7}{10}\times 11[/tex]
[tex]l=7.7cm[/tex]
