Answer:
[tex]RP=11.2\ ft[/tex]
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
[tex]\frac{RP}{CA}=\frac{QR}{BC}[/tex]
substitute the given values
[tex]\frac{RP}{16.8}=\frac{14}{21}[/tex]
solve for RP
[tex]RP=\frac{14}{21}(16.8)[/tex]
[tex]RP=11.2\ ft[/tex]
