Gina looks at the architectural plan of a four-walled room in which the walls meet each other at right angles. The length of one
wall in the plan is 17 inches. The length of the diagonal of the floor of the room in the plan is approximately 18.79 inches. Is the room in the shape of a square?
The shape of the room is not a square. Pythagorean Theorem: 17^2+17^2= 578, square root 578 and you'll get 24.04. The length of the diagonal of the floor of the room in the plan should have been 24.04 in order to be a square.
