In the rectangle below, sketch the position of the ribbons and outline a right triangle with a diagonal of the rectangle as the hypotenuse. Then, label the right triangle below the rectangle with the appropriate lengths from the problem.

The length of the ribbon needed to cross from one corner of the rectangle to the other corner is 7 1/2 feet.
The length of the ribbon needed can be determined using the Pythagoras theorem.
The Pythagoras theorem: a² + b² = c²
where
a = length
b = base
c = hypotenuse
√4.5² + 6²
√36 + 20.25 = 7.5 feet
