Answer:
79 ft 
Step-by-step explanation:
Golden rectangle side ratios   1 : (1+sqrt5 )/2
       (approx  1: 1.618)
15 + 15   +  2*15*1.618 = <u>~79 ft </u>
BUT perhaps the 15 is the 1.618 side 
15/1.618 + 15/1.618   + 15 + 15   ~ 49 feet

Answer:
13.3
Step-by-step explanation:
f² = e² + g² - 2egcos(F)
f² = 9² + 18² - 2(9)(18)cos(46)
f² = 175.8974029
f = 13.26263128
