A man walked diagonally across a square lot. Approximately, what was the percent saved by not walking along the edges?
Options:
A . 20
B . 33
C . 30
D . 24
Answer: Option C
Let the side of the square(ABCD) be x metres. Then, AB + BC = 2x metres. AC = √2x = (1.41x) m. Saving on 2x metres = (0.59x) m. Saving % = ❨ 0.59x x 100 ❩% = 30%
