... President of the neighbour country called the Gardener and ordered him to place those 4 plants in the garden in such a way that those should be at equal distance from each other. The Gardener tried his level best to place those plants at equal distance from each other but failed. The Gardener is too much worried as he has to obey the order of the President in any case. You please help and tell how the problem of the Gardener can be solved
