I don't think binary search is needed . Since arcs are part of same circle , so first determine the radius r. From triangle (r,l/2,w/2 ) we get r^2=(l/2)^2 + (w/2)^2 From (r,r,w) triangle sector angle from cos law. then arc= angle *r so the perimeter of stadium is 2*l + 2*arc and you can get ratio=400/(2*l + 2*arc) then ans is l*ratio , w*ratio
Hope it helps . :)
