Mathematics Question and Solution
Notice;
The single side length of the ascribed regular hexagon, the inscribed regular pentagon, the inscribed square, and the inscribed equilateral triangle are equal.
It is 39 units.
Therefore;
Area green is;
Area regular hexagon with single side length 39 units - Area regular pentagon with single side length 39 units + Area square with single side length 39 units - Area equilateral triangle with single side length 39 units.
= (9126/4tan(180/6)) - (7605/4tan(180/5)) + (39*39) - ½(39)²sin60
= 3951.67391747 - 2616.8461263 + 1521 - 658.612319578
= 2197.21547159 square units.
