Answer:

y=3

Step-by-step explanation:

Given:  Parallelogram ABCD is a rectangle.

            AC=5y-2 and BD=4y+1

To find: Value of <em>y</em>

Solution: It is given that ABCD is a rectangle, and we know that the opposite sides of a rectangle, and the diagonals of a rectangle are always equal.

As, AC and BD are the diagonals of the rectangle, both will be equal.

So, on equating AC and BD we have,

AC=BD

5y-2=4y+1

5y-4y=1+2

y=3

Hence, the value of <em>y </em>is 3.

Because diagonals of a parallelogram are equal, set both problems equal to one another. Solving, you should get y=3
