two similar figures have lengths in the ratio of 7/4. Give the ratios of parimeters and areas?

perimeter calculation is a linear measurement, so the perimeters are in the ratio of 7:4
but the area of two similar figures is in the ratio of the square of their sides, so
the areas are in the ratio of 49:16
