Answer 1

Answer:

Length of diagonals = 4 cm and 5 cm

aluminium foil used to cover a single pack of sweet = Area of rhombus

= 1/2 * d1 * d2

= 1/2 * 4 * 5

= 1/2 * 20

= 10 cm square

Area of aluminium foil used to cover 400 such boxes = 10 * 400

                                                                                             = 4000 cm square
