1st figure= 20m, 2nd figure=34m

20:34

1:34/20

Area=19.6

So, 19.6*34/20=\({33.32}=\boxed{33.3}\)

Notice that the perimeter of the second figure  / perimeter of the first figure will be the linear scale factor  =

 

34 / 20  =   17/10   = 1.7

 

So....the area of the second figure will be =

 

area of first figure  * (linear scale factor)^2  =

 

19.6  * (1.7)^2  =

 

56.6  m^2
