9.   The scale factor between the larger figure and the smaller one is   =  10 : 8    =   5 : 4     

Since perimeter is a linear measure, it has the same ratio, 5 : 4

The area ratio is  the square of the scale factor  =  25 : 16 

 

10.  The scale factor  between the larger figure and the smaller one is 57 : 24

So.....the area of the larger figure is   (scale factor)^2  as much as that of the smaller figure

So....

 

564  (57/24)^2  ≈  3181  m^2
