Question 2

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?

Answer 1

The total length of tape required = Perimeter of the rectangle.

= 2 (length + breadth).

= 2 (40 + 10).

= 2 $\times$ 50.

= 100 cm.

= 1 m

Thus, the total length of tape required is 100 cm or 1 m.
