QUESTION:-

The lid of a rectangular box of sides 40 cm by 10 cm is sealed all around with tape. What is the length of the tape required?

GIVEN:-

• length = 40cm

• breadth = 10cm

TO FIND:-

• the length of the tape required = ?

FORMULA USED:-

• [tex]2 ( l + b )[/tex]

SOLUTION:-

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

                                                           = 2 ( 40 + 10 ) cm

                                                           = 2 (50) cm

                                                           = 100 cm

hence, the length of the tape required is 100 cm
