Video Summary

The square is built from a central 7 cm black square, four identical white rectangles, and four identical gray rectangles. Using the white rectangle’s longer side of 15 cm, its width is 15 - 7 = 8 cm. This makes the combined top section 7 + 8 + 8 = 23 cm. Since each gray rectangle has longer side 29 cm, its width is 29 - 23 = 6 cm. Adding that width to the 29 cm side gives the full side length of the outer square: 29 + 6 = 35 cm. So, the side length of square ABCD is <strong>35 cm</strong>.
