Question

painting 40 cm long and 30 cm wide is painted on a card board such that there is a margin of 2cm along each of its sides . Find the margin ​

Answer 1

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.
