Answer 1

Answer:

Summary: The length of the tape required to seal the lid of a rectangular box of sides 40 cm by 10 cm with tape will be 100 cm.

Answer 2

SOLUTION:-

length = 40 cm

breadth = 10 cm

perimeter of a rectangular box = 2 ( l + b)

                                                     = 2 ( 40 + 10 )

                                                     = 2 (50)

                                                     = 100 cm

hence, the length of a tape required is 100 cm

hope it helps :D
