Answer: Option C
Solution(By Examveda Team)
Let the side of the square(ABCD) be x metres.Then, AB + BC = 2x metres
AC =$$\sqrt 2 $$ x = (1.41x) m
Saving on 2x metres = (0.59x) m
$$\eqalign{ & {\text{Saving}}\,\% = \left( {\frac{{0.59x}}{{2x}} \times 100} \right)\% \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 30\% \,\left( {{\text{approx}}} \right) \cr} $$
