I won't draw with a graph. I can directly use Helen's theorem to find a triangle with an area of 9.5 and a total area of 26+25+17+9.5 * 4 =106.

The three side lengths of the middle triangle are the root number 26,5 and the root number 17 respectively. Using Helen's theorem, it is known that the area of three sides is 9.5, and the areas of four triangles are equal, and they all add up.

Drawing can connect the points of 1*5, 3*4, 1*4 into a 4*5 grid, forming a middle with an area equal to 4 * 5-1* 5/2-1* 4/2-3 * 4/2.
