A man had a window a yard square, but it let in too much light. He blocked up half of it. After this he still had a square window a yard high and a yard wide. How did he do it?

Any shape that's 4.5 square feet in area that fits within the yard square could be used to block the light, such as a 2 ft x 2ft, 3 in, rectangle, placed in any orientation within the yard square.
