Answer 1

The correct option is C 60

To find out the number of stamps that can be pasted on the wall, we will divide the area of the wall by the area of the each stamp.

$\text{Area of each stamp =}3\times 3$
$=9sqin$

Area of wall = 540 sq in

$\text{Number of stamps pasted =}\frac{\text{Area of wall}}{\text{Area of stamp}}$

$=\frac{540}{9}$
$=60$
