Before a football game can be played, the playing field must be painted. Football fields are rectangles. How can a couch guarantee that the field he is about to paint is a rectangle and not a parallelogram using only a tape measure?

Answer :

Answer and Step-by-step explanation:

The only way the coach can guarantee that he is about to paint a rectangle using only a tape measure is by measuring opposite sides of the field and be assured that they are equal.

This is because the opposite sides of a rectangle are always the same, else it is not a rectangle.
