A rectangular sheet of paper is `(12) 1/2 cm` long and `(10) 2/3 cm` wide. Find its perimeter.

Explanation

To find the perimeter of a rectangular sheet of paper that is \(12 \frac{1}{2} \, \text{cm}\) long and \(10 \frac{2}{3} \, \text{cm}\) wide, we will follow these steps:

### Step 1: Convert the mixed numbers to improper fractions.

1. **Length**:
\[ 12 \frac{1}{2} = 12 + \frac{1}{2} = \frac{12 \times 2 + 1}{2} = \frac{24 + 1}{2} = \frac{25}{2} \, \text{cm} \]
