Help me i need these done ;-;

Okay, so the square all sides are 7 so the diagonal using the 45-45-90 triangle theorem you can find that the diagonal is 7 times the square root of 2.  The diagonal of the rectangle can be found because it will divide the rectangle into 2 30-60-90 triangles.  The hypotenuse is 2 times the smallest side in a 30-60-90.  We know that the smallest side is 7.  So the hypotenuse is 14 (I think there is an error in the question).  We know this using the 30°-60°-90° Triangle Theorem.  Because 14 is not 2 times 7 times the square root of 2.  Anna is incorrect.  I think.
