Rectangle No. 1 has a length of 7 cm and a width of 4.5 cm. If rectangle No. 2 is congruent to rectangle No.1, what is the perimeter of rectangle No. 2?

If the rectangles are congruent, they have the same perimeter.
Using the formula for the perimeter of a rectangle yields that the perimeter of Rectangle 1 is 23 cm.
Thus, the perimeter of Rectangle 2 is also 23 cm.
