Answer:
Area of remaining chart paper =9m^2
length of chart paper=4m
breadth of chart paper=3m
Area of chart paper=l×b=4×3=12m^2
length of cut out strip=1m
breadth of cut out strip=3m
Area of cut out strip=l×b=1×3=3m^2
Area of remaining chart paper=Area of chart
paper-Area of cut out strip
=12-3=9m^2
Hence, area of remaining chart paper is 9m^2.
Hope it will help you.
