Area green is;
Area rectangle with length 18 units and width 16 units - Area triangle with height 12 units and base 16 units - Area semi circle with radius 10 units.
= (18*16) - ½(16*12) - ½(...
Area Blue is;
Area square with side length 4 cm - Area quarter circle with radius 4 cm + 2(area square with side length 2 cm).
= (4*4)-(¼*4*4π)+2(2*2)
= 16-4π+8
= 24-4π
= 4(6-π) cm²
Let a be the side length of the regular hexagon.
sin30 = b/a
b = ½(a) cm.
c = 2b+a
c = 2a cm.
cos30 = d/a
d = ½√(3)a cm.
e = ½(162√(3)) cm²
e = 81√(3) cm²
e is half the area of the...
a = ⅓(4L)-L
a = ⅓(L) cm.
tanb = L/(4L/3)
b = atan(3/4)°
3/4 = c/(⅓(L))
c = ¼(L) cm.
d = 180-45-atan(3/4)
d = (45+atan(4/3))°
It implies;
((4L/3)/sin(45+atan(4/3))) = (e/sin(atan(...

Let the single side length of the square be 2 units.
Therefore;
Area square is;
2²
= 4 square units.
Calculating area green.
It is;...
White area is;
Area sector with radius 6 cm and angle 120° + Area sector with radius 2 cm and angle 60°
= (120*36π÷360) + (60*4π÷360)
= 12π + ⅔(π)
= ⅓(38π) cm²
Green area is;
Area circle with radius 5 units + 2(area sector with radius 20 units and angle 60°) - Area equilateral triangle with side 20 units.
= π(5²) + 2(60÷360*20²π) - ½(20²)sin60
= 25...
Let the radius of the inscribed circle be r.
The radius of the semi circle is 5 units.
Therefore;
(2r)² + r² = 5²
4r² + r² = 25
r = √(5) units.
Therefore shaded area/area blue is;...

AB is 2 cm.
BC is 6 cm.
The single side length of equilateral triangle BDE is;
= ⅓(16√(3)) cm.
Therefore;
Area Orange is;
Area trian...
sin30 = a/12
a = 6 cm.
Where a is the height of the green regular triangle.
sin60 = 6/b
½√(3) = 6/b
b = 12/√(3)
b = 4√(3) cm.
b is the side length of the green regular triangle.
tan30 =...
