Answer:

Given,

L of rectangle= 18

B of rectangle= 11

Side of square stamp= 9

Area of a rectangle=

$l \times b \\ = 18 \times 11 \\ = 198$

Area of square=

$side \times side \\ = 9 \times 9 \\ = 81$

No of stamps required to cover envelope=

$\frac{18 \times 11}{9 \times 9} \\ = \frac{22}{9} \\ = 2.4$
