Answer:

Ratio of perimeter = 5:4 and Ratio of area =25:16.

Step-by-step explanation:

In two similar figure the ratio of perimeter is equal to the ratio of the sides and Ratio of area is equal to the square of the ratio of their sides.

In the given rectangles the ratio of the sides = 10:8 which in simplified form is 5:4.

Hence Ratio of perimeter = Ratio of sides =5:4.

Ratio of area = Square of the ratio of sides =[tex]5^{2} :4^{2} =25:16.[/tex]
