HURRY PLEASE :)!!

The widths of two similar rectangles are 10 cm and 15 cm. What is the ratio of the perimeters? Of the areas?

the ratio of the areas is the ratio of the squares of the sides ( which is 10:15 or 2:3) so the answer is
2^2 : 3^2 = 4:9.

The ratio of the perimeters = ratio of corresponding side = 2:3.
