Raskin M.A.

A square frame was placed on the ground, and a vertical pole was set up in the center of the square. When a fabric was stretched over this structure, a small tent was formed. If two such frames are placed side by side, a vertical pole of the same length is placed in the center of each, and a fabric is stretched over the top, a larger tent is formed. It took 4 square meters of fabric for the small tent. How much fabric will be needed for the large tent?

Let's draw lines on the fabric as shown in the left figure. Notice that if we rearrange two triangles, we get two tents equal to the small tent (right figure). Therefore, the answer is $2 \cdot 4=8$.
