उत्तर

If the area occupied by 15 postal stamps is 60 cm2, then the area occupied by 120 such postal stamps will be 480 cm2.

Explanation:

∵ The area occupied by 15 postal stamps = 60 cm2.

∴  The area occupied by 1 postal stamp = `60/15` = 4 cm2

Similarly, the area occupied by 120 such postal stamps = 4 × 120 = 480 cm2
