Let the square side be 2 units.
Area square is;
2²
= 4 square units.
Calculating Area A.
a² = 2²+1²-2*2*1cos45
a = √(5-2√(2)) units.
(√(5-2√(2))/sin45) = (2/sinb)
b = asin(√(2)/(√(5-2√(2))))°...
Let the square side be x.
x²+(x-4)² = a²
a = √(2x²-8x+16)
b² = 2²+(x-2)²
b = √(x²-4x+8)
It implies;
(½(a))²+6² = b²
½(x²-4x+8)+36 = (x²-4x+8)
x²-4x+8+72 = 2x²-8x+16
x²-4x-64 = 0
(x-2)² = 68...

Let the square side be a.
2(a-14)² = 14²
(a-14)² = 98
a = 14+7√(2) units.
Green area length and width is;
Length = 14+7√(2)-18
= 7√(2)-4 units.
Width = 14+7√(2)-10
= 4+7√(2) units.
Green area is...
Let the height of the quadrilateral with parallel sides 7 cm and 9 cm be a.
b =√(a²+4) cm.
c = ½√(a²+4) cm.
d = √((½√(a²+4))²-1)
d = √(¼(a²+4)-1)
d = √(¼(a²))
d = ½(a) cm.
½(a) = 8
1 = e,...

Radius, r of the inscribed semi circle is 6 cm.
sin60 = a/6
a = 3√(3) cm.
b = 12-a
b = (12-3√(3)) cm.
tanc = 3/(12-3√(3))
c = 23.793976887°
c = angle GCB.
d = 180-60-23.793976887
d = 96.20602311...
