If the ratio of the corresponding side lengths of two similar rectangular tables is 4 and 5 what is the ratio of the perimeter?

The ratio of the perimeters of two similar shapes is the same as the ratio of their corresponding side lengths. Since the ratio of the side lengths of the two rectangular tables is 4:5, the ratio of their perimeters will also be 4:5. Therefore, the ratio of the perimeter of the first table to the perimeter of the second table is 4:5.
