Length of paper required to make 1 envelop = 18 CM
Breadth of paper required to make 1 envelop = 12 CM
Area of paper required to make 1 envelop = 216 cm^2
Given length = 3m 24cm = 324 CM
Given breadth 1m 72 CM = 172cm
Area = 324×172 = 55728 cm^2
therefore,
required no. of envelops = 55728/216
= 258
