Draw a sketch. It helps if it is somewhat to scale; but it's not critical.

Draw the segments through W parallel to the sides of the rectangle, dividing two sides of the rectangle into parts of lengths a and b, and dividing the other two sides of the rectangle into two parts of lengths c and d.

If you use the lengths of WJ, WR, WL, and WM with the Pythagorean theorem in terms of a, b, c, and d, you will discover the answer to the problem can be found as follows:
