Question

Sixteen L shapes like the ones below have been fitted into a rectangular shape. Each L has one hole, and there are four of each type in the rectangle. No two pieces of the same type are adjacent – even at a corner. They fit together so well that the spaces between pieces do not show. From the locations of the holes, can you tell where each L is?
