A man walked diagonally across a square plot. Approximately what was the percent saved by not walking along the edges?

let the side of the square be x meters
length of two sides = 2x meters
diagonal =  $2x$= 1.414x m

saving on 2x meters = .59x m

saving % =  $\frac{0.59x}{2x}*100$%

= 30% (approx)
