Okay, the total is 69 units.
(3y)+(12)+(y+1)+(2y+3)+(11)=69
Combine like terms
6y+27=69
Subtract 27 from both sides.
69-27=42
Divide by 6 on both sides
42/6=7
y=7
Plug it into the length of AB
2(7)+3
14+3
length of AB=17

Answer:
6√2
Step-by-step explanation:
So the diagonal of a square is equal to √2 times the length of the side of the square. Working backwards that would mean: 12/√2 = side of square
this means that the side of the square is 6√2
The side of the square is also the diameter of the circle.
