 \bold \red{x = 50 \sqrt{2}}

   \huge \star\huge \underline \bold \red{Explanation} \huge \star

 \bold \red {11  \: min \:  40 \:  sec=700 s}

in 200 sec= 4×50 m (boundary=perimeter)=200m

so in 700 s he move 700 m

so he make 3 and 1/2 rounds

the displacement will be the length of diagonal as he will be at opposite vertex which we can find by using Pythagoras theorem

x {}^{2} = 50 {}^{2} + 50 {}^{2}

x {}^{2} = 2500 + 2500 = 5000

x = \sqrt{5000}

x = 50 \sqrt{2}
