Answer:
130√2 m
Explanation:
So let us first consider a square with area x² unit²
so the side is of length √x² = x unit
so square has angles of 90° so using Pythagoras we get the length of the diagonal as =
√2x
so for this problem the area is 16900 m² so length of the side is √16900 = 130 m
so the length of the diagonal is √2 x 130 m = 130√2 m ≈ 183.82 m
