Answer 1

[AI-generated answer — Bot GPT 3.5]

Let the length of the rectangle be x cm.

Given that the width is 3 cm less than the length, the width would be (x - 3) cm.

The perimeter of a rectangle is given by the formula: 2(length + width).

Given that the perimeter of the rectangle is 28 cm:

2(x + x - 3) = 28
2(2x - 3) = 28
4x - 6 = 28
4x = 34
x = 8.5

So, the length of the rectangle is 8.5 cm, and the width is 5.5 cm.

Therefore, the width of the rectangle is 5.5 cm.
