To provide an accurate solution, I need to understand the dimensions of Mia's rectangular garden and how she plans to divide it into two triangular areas. However, since I can't see the diagram, I can offer some general guidance on how to calculate the length needed for the fence.
If Mia wants to divide her rectangular garden (with length \(L\) and width \(W\)) into two triangular areas, she might place the fence diagonally from one corner of the rectangle to the opposite corner. The length of the fencing will then be the length of the diagonal.
You can find the length of the diagonal \(D\) using the Pythagorean theorem:
\[ D = \sqrt{L^2 + W^2} \]
After calculating the length of the diagonal, round your answer to the nearest hundredth.
If you provide me with specific measurements of the garden, I can compute the exact length of the fence needed.
