    I'm taking radius to be half of the side length. Then one side is 26 cm and the area of a square is the length of a side squared. A=26^2=676 C) 676

    I guess radius should be half of the diagonal in this case.

    in that case the side length is 26/sqrt(2) and we have an area of 338

    what has your teacher used when they talked about radius of a square? I geuss it would make more sense that it is the measure from the center of the object to the circle your polygon is inscribed in. I would go with half of the diagonal
