There's a square shaped field whose area is 121 meter^2. There's a rectangle shaped road along the diagonal of the field. If the breadth of the road is 1 meter. What's the area of the road?

The area of the square-shaped field is given as \(121 \, \text{m}^2\). To find the area of the rectangular road along the diagonal of the square, we first need to find the length of the diagonal and then use the breadth of the road (which is 1 meter) to calculate the area.

### Step 1: Find the side length of the square
The area \( A \) of a square is related to the side length \( s \) by the formula:
\[
A = s^2
\]
Given that \( A = 121 \, \text{m}^2 \), we can solve for \( s \):
\[
s = \sqrt{121} = 11 \, \text{m}
\]
So, the side length of the square is \( 11 \, \text{m} \).

### Step 2: Find the diagonal of the square
The diagonal \( d \) of a square is related to the side length by the formula:
\[
d = s\sqrt{2}
\]
Substituting \( s = 11 \, \text{m} \):
\[
d = 11\sqrt{2} \, \text{m} \approx 11 \times 1.414 = 15.556 \, \text{m}
\]
So, the length of the diagonal is approximately \( 15.556 \, \text{m} \).

### Step 3: Calculate the area of the rectangular road
The area \( A_{\text{road}} \) of the rectangular road is given by the product of its length (which is the diagonal of the square) and its breadth (which is \( 1 \, \text{m} \)):
\[
A_{\text{road}} = d \times \text{breadth} = 15.556 \times 1 = 15.556 \, \text{m}^2
\]
Thus, the area of the road is approximately \( 15.556 \, \text{m}^2 \).

### Final Answer:
The area of the road is approximately \( 15.56 \, \text{m}^2 \).
