Question 1131399
<br>
The question can't be answered as you show it....<br>
Now, if it is true that ABCD and TVYN are similar figures, then the answer is easy.<br>
The ratio between any given pair of corresponding linear measurements between two similar figures is the ratio between ALL corresponding linear measurements.<br>
Specifically, if the ratio of the perimeters is 5/7 and the figures are similar, then the ratio of AD to TN is also 5/7.
