☆ Solution ☆

Given :-

• The lid of a rectangular box of sides 40 cm by 10 cm is sealed all round with tape.

To Find :-

• What is the length of the tape required?

Step-by-Step-Explaination :-

Length of the tape = Perimeter of rectangle

So,

As we know that :-

Perimeter of rectangle = 2 ( l + b )

Putting the respective value,

Perimeter of rectangle = 2 ( 40 + 10 )

Perimeter of rectangle = 2 × 50

Perimeter of rectangle = 100 cm or 1 m

Hence,

The length of the required tape 100 cm or 1 m.
