A square wire of side `3.0 cm` is placed `25 cm` away from a concave mirror of focal length `10 cm`. What is the area enclosed by the image of the wire ? The centre of the wire is on the axis of the mirror, with its two sides normal to the axis.

Explanation

To solve the problem step by step, we will use the mirror formula and the concept of magnification.

### Step 1: Identify the given values
- Side of the square wire (s) = 3.0 cm
- Distance from the mirror (u) = -25 cm (negative as per the sign convention for mirrors)
- Focal length of the concave mirror (f) = -10 cm (negative for concave mirrors)

### Step 2: Use the mirror formula
