Answer 1

Hi Tinki != 
____________________________________________________________
Cardboard I
Length  =  11/5 m 
breadth =  6/5 m
Area     =  l x b  = 66/ 25 m² = 
____________________________________________________________
Cardboard II 
Length = 16/5 m 
Breadth = 12/5 m 
Area      = 192/25 m²
____________________________________________________________

Divide Cardboard I and II area into 10 parts 
Then each part area of Cardboard I  = 66/250 m²
And each part area of cardboard II    = 192/250 m²
___________________________________________________________
Total area of cardboard = 5 x each part area of Cardboard 1 + 3x each part                                               area of Cardboard II
                                      = 5 x 66/250 + 3x 192/250 
                                      = 330/250 + 576/250 
                                      = (330  + 576 )/250 
                                      = 906/250 m² 
                                      = $3 \frac{156}{250}$ m²
