Let the radius of the inscribed green circle be r.
Calculating r.
(1-r)² = 2(r)²
1-2r+r² = 2r²
r²+2r-1 = 0
(r+1)² = 2
r = (√(2)-1) cm.
Therefore;
Area green inscribed circle is;
πr²
= π(√(...

Our Solution.
Let the radius of the semi circle be r.
Calculating r.
It implies;
(r-5)² = 5²+(r-6)²
r²-10r+25 = 25+r²-12r+36
-10r = -12r+36
2r = 36
r = 18 units.
Blue Area is;
Area semi ci...

Let the inscribed regular pentagon side be 1 unit.
Area small/inscribed pentagon is;
0.5*5(1/(2tan(180/5)))
= 1.72047740059 square units.
Calculating Shaded Area.
a² = 2-2cos(60+108)
a = 1.9890...
Let the side of the regular pentagon be 1 unit.
a = 360-2(108)-90
a = 54°
tan72 = b/0.5
b = 1.53884176859 units.
tan54 = 1.53884176859/c
c = 1.11803398875 units.
d = c-0.5
d = 0.61803398875 unit...

Let the side of the regular pentagon be 1 unit.
Notice;
The regular pentagon side is equal the regular heptagon side.
a = ⅐(180*5)
a = ⅐(900)°, the single interior angle of the regular heptagon....
