Answer:
Length (L) = 50 m
Explanation:
Given information,
→ 400 m long fencing wire is required to surround square flower garden 2 times.
Now the fence taken for 1 time,
→ 400 ÷ 2
→ 200 m
Formula we use,
→ P = 4 × L
[Perimeter of square]
Then the length of the garden is,
→ P = 4 × L
→ 200 = 4L
→ 4L = 200
→ L = 200/4
→ [ L = 50 m ]
Hence, length of garden is 50 m.
