Which of the following lines is a line of symmetry on the figure below?

Step 1: Calculate the perimeter of the garden. The garden is a rectangle with length $L = 57\, \text{m}$ and width $W = 36\, \text{m}$. The length of wire required to fence the garden is its perimeter. The formula for the perimeter of a rectangle is $P = 2 \times (L + W)$. $P = 2 \times (57\, m + 36\, m)$ $P = 2 \times (93\, m)$ $P = 186\, m$ The length of wire required is $186\, \text{m}$.

The final answer
