Given
A sheet of paper 3 m 24 cm by 1 m 72 cm.
Each envelope requires a piece of paper of size 18 cm by 12 cm.
Find the area of sheet of paper :-
Area of rectangle = (Length × Breadth) sq. units
= (324 × 172) cm²
= 55728 cm²
Find the area of each envelope :-
Area of each envelope = (18 × 12) cm²
= 216 cm²
Number of envelopes = Area of paper / Area of each envelope
= 55728 / 216
= 258
Hence,
258 envelopes can be made.
