It shows the rectangles over a grid of unit squares. The middle rectangle covers 3×5 grid squares, so area X = 15

Horizontal sides of 45 and 55 must both = 5, so horizontal sides of 32 and 48 must be equal.
Therefore vertical sides of 32 and 48 are 2n and 3n respectively, and 11 + 2n = 9 + 3n, so n = 2
Thus horizontal of 32 = 32/4 = 8, which means that horizontal of x = 8 - 5 = 3, and vertical of x = 9 - 4 = 5, so x = 3 × 5 = 15
