Tomas Kline · Answer 1

The first thing we are going to assume is that we have the perimeter of the lid, which is given by:

P = 5 cm

We will also assume that the box is square, then the lid is also square.

Therefore the perimeter is given by:

P = 4L

Where,

L: side

We cleared L:

L = P / 4

Substituting:

L = 5/4 cm

L = 1.25 cm

Answer:

the length of the lid is:

L = 1.25 cm
