<span>The question is asking to state if those statements are true or false. First we have to mention some definitions: Parallelogram is a 4-sided flat shape with straight sides where opposite sides are parallel. And Parallelograms are: Square, rectangle and Rhombus. All Squares are Rectangles and all Rectangles are not Squares. Answers are: 1. All parallelograms are squares ( FALSE ) 2. All squares are parallelograms ( TRUE ) 3. All trapeziods are scalane ( FALSE ). 4. All squares are rhombuses ( TRUE ). 5. All rhombuses are squares ( FALSE ) 6. All rectangles are squares ( FALSE ). 7. All squares are rectangles ( TRUE ). </span>
The answer would be 11.6619037897 because if you make a triangle out of it the sides are 10 and 6 so a^2 + b^2 = c^2 and you get 136 and if you find the square root of that it is <span>11.6619037897</span>
