A man walked diagonally across a square plot. Approximately what was the percent saved by not walking along the edges? Correct Answer 30%

let the side of the square be x meterslength of two sides = 2x metersdiagonal = 2x= 1.414x m

 

saving on 2x meters = .59x m

 

saving % = 0.59x2x*100%

 

= 30% (approx)
