Answer:
453/125 square meter.
Step-by-step explanation:
Area of first cardboard =11/5 mx 6/5m
= 66/25 square meter
Area of cardboard divided into 10 equal parts
66/25÷10
33/125square meter
If it is made using 5 smaller pieces from fist cardboard
=33/125 x 5
=33/25 square meter
Area of second cardboard=16/5 m x 12/5m
192/25 square meter
Area of second cardboard also divided in 10 equal parts
192/25÷10
96/125 square meter
If it is made using 3 smaller pieces from the second cardboard
=96/125 x 3
=288/125 square meter
Total area of the first and second cardboard
=33/25 square meter + 288/125 squre meter
=(165 + 288)/125
453/125 square meter
