Area of the park= 350(200)=70,000 m^2;

Area of the pathway= 74,464m^2-70,000m^2
                                =4,464m^2;

Pathway area:
    4,464={[350+2x]x}2+400x;
4x^2+1100x-4,464=0
/4;

x^2 + 275x -1116=0;

by Quadratic form;

x=8/2=4;

pathway width=4m..ans

thank you so much, it's very big help. :D
wait, where did u get the 2x?
one lenght is x +350 + x=350+2x multiply by width of x then the answermust be multiplied by two( top and bottom arrangement)
do you know what is the formula?
its all about Lenght x width..if i have enough time i'll send u the diagram...
