The length and width of a rectangle form a
right triangle with the diagonal as hypotenuse.
L=length; W=width; D=diagonal
L%5E2%2BW%5E2=D%5E2
sqrt%28L%5E2%2BW%5E2%29=D
sqrt%2840%5E2m%5E2%2B9%5E2m%5E2%29=D
sqrt%28100m%5E2%2B81m%5E2%29=D
sqrt%281681m%5E2%29=D
41m=D ANSWER: The measure of the diagonal is 41 meters.
