Answer:
y = 7
Step-by-step explanation:
Given the parallelogram, ABCD is a rectangle and we know that the length of two diagonals of a rectangle are the same.
Now, given that the diagonal of the rectangle ABCD, AC = 6y - 1 and BD = 4y + 13
Then, we have AC = BD
⇒ 6y - 1 = 4y + 13
⇒ 2y = 14
⇒ y = 7 (Answer)
