Sin 23° = Opposite/Hypotenuse = b / c
0.39 = b / 30
b = 0.39 · 30
b = 11.722 cm
Area of a triangle:
A = 1/2 b h
A = 1/2 · 11.722 · 27.6
A ≈ 161.7 cm²

<h3>The Mondrian's work</h3>

The First division that was divided into 9 equal parts has = 1 coloured red.

The second division is 8 remaining

uncoloured squares into 9 equal squares = 8×9= 72boxes

The number of boxes that was coloured yellow =8 boxes

The remaining uncolored boxes which is = 72 - 8 = 64 boxes

The third division is the division of each remaining uncolored boxes into 9. That is 64 × 9 = 576

The number of boxes that was coloured blue = 64 boxes

Therefore the number of central squares that has been coloured = 1 + 8 + 64

= 73 boxes
