Question

6. Gary has a rectangular painting that is 21 inches

wide and 36 inches long. He wants to place wire
in the shape of an X on the back of the painting
along its diagonals so that he can hang the
painting on the wall. Which is the best estimate
of the total amount of wire Gary will need?
42 inches
84 inches
57 inches
114 inches

Answer 1

84 inches is your answer.

Use Pythagorean theorem to solve for the diagonal of the rectangle, then multiply by 2 because it’s an X.
