Mathematics Question and Solution
Sir Mike Ambrose is the author of the question.
The base/length of the rectangle with height or width 4 units is 3√(3) units.
Therefore calculating red area (right-angled triangle with hypotenuse 4 units).
The right-angled triangle's height, x is;
Cos27.45707609594 = x/4
x = (4cos27.45707609594) units.
It implies;
Area Red exactly in decimal is;
Area triangle with height (4cos27.45707609594) units and base (4sin27.45707609594) units.
= ½*(4cos27.45707609594)*(4sin27.45707609594)
= 3.27316688045 square units.
