Answer:
Area of margin = 296 CM sq.
Step-by-step explanation:
First add - 40+2+2= 44
Then add - 30+2+2 = 34
Area of small rectangle = l x b
= 40 x 30
= 1200
Area of large rectangle = l x b
= 44 x 34
= 1496
Area of margin = Area of large rectangle - Area of small rectangle
= 1496-1200 = 296
Area of margin = 296 CM sq.
