A dog runs around the triangle in such a way that the shortest distance of the dog from the triangle is exactly 1 meter. The total distance covered (in meters) by the dog in one round isThe lengths of the sides of a triangle are x,21x, 21x,21 and 404040, where xxx is the shortest side. A possible value of xxx is:
