Two sides of the parallelogram are vertical and the other two sides are diagonals of a square of the grid. Divide both sides by x.

Step 1 Use the Ceveloping Theorem to find the height h. Use the grid to find the area of the shaded kite. You can use the Area Addition Postulate quadrillaterals see that a parallelogram has the same area as a rectangle with the same base and height. Use the Pythagorean Theorem to find x and y.
