Please help, I don't understand part a or b.

Serggg [28]

Part A
25-9=16
16/2=8
The length of the rope holding the top right corner of the banner to the post is 8 feet long

Part B
13-9-2= 2 for width
25-8=16 16/2=8 for length
Use the Pythagorean Theorem
$a^{2}$ + $b^{2}$ = $c^{2}$
$8^{2}+ 2^{2}= c^{2}$
64+4= $c^{2}$
68= $c^{2}$
$\sqrt{68}= \sqrt{c}$
34=c
The length of the rope from the bottom right corner of the banner to the post is 34 feet
