Answer:
हम उम्मीदों की दुनियां बसाते रहे;
वो भी पल पल हमें आजमाते रहे;
जब मोहब्बत में मरने का वक्त आया;
हम मर गए और वो मुस्कुराते रहे।”तेरे सीने से लगकर, तेरी आरजू बन जाऊँ,
तेरी साँसो से मिलकर, तेरी खुशबु बन जाऊँ,
फासले ना रहें कोई हम दोनो के दरमिआँ,
मैं, मैं ना रहुँ, बस तु ही तु बन जाऊँ ।

Answer:
Length of painted cardboard=36 cm and breadth of painted card =22cm
Since, there is a margin of 2.5cm long from each of its side.
Therefore reduced length
=36−(2.5+2.5)=36−5
=31cm
And reduced breadth
=22 cm−(2.5+2.5 )=22-5
=17 cm
∴ Area of margin=Area of cardboard(ABCD)−Area of cardboard(EFGH) to
=(AB×AD)−(EF×EH)
=(36×31)−(22×17)
=1116-374
=742 cm sq.
Thus, the total area of margin is 742cm square.
