Answer:
41 2/3 feet
Step-by-step explanation:
The sum of wall lengths (in feet) is ...
(12 1/4) + (10) + (12 1/4) + (10 -2 5/6)
= (12 + 10 + 12 + 8) + (1/4 + 1/4 - 5/6)
= 42 + (3/12 + 3/12 -10/12)
= 42 - 4/12 = 42 - 1/3
= 41 2/3 . . . feet

AD = 9x + 3
DC = 57
ADC is a line, which is perpendicularly bisected by BD.
Thus AD = DC
9x + 3 = 57
9x = 57 – 3
9x = 54
x = 54/9

18 divided by 2/3
