1)L= LENGTH OF WIRE FROM MID POINT OF LONG SIDE
L^2=30^2 + 25^2
L^2=900+625
L= SQR(1525)
L=39.05

2) S=LENGTH OF WIRE FROM MID POINT OF SHORT SIDE
S^2=16^2 + 25^2
S^2=256 +625
S=SQR(881)
S=29.68

3)C=LENGTH OF WIRE FROM CORNER
B = DISTACE FROM THE BASE OF THE POLE TO THE
EDGE

B^2=16^2 +30^2
B^2=256+900
B=SQR(1156)
B=34

C^2=34^2 + 25^2
C^2=1156+625
C=SQR(1781)
C=42.20

*** I FIXED THEM! MY FIRST ANSWERS WERE WRONG. THESE ARE RIGHT TO THE BEST OF MY KNOWLEDGE!
29.7 ft to long
39.1 ft to short
42.3 ft to corners

Those numbers are, of course, rounded.
