The formula for calculate the area of a triangle is:
Where b () is the base and h () is the height.
The formula for calculate the area of a semicircle is:
Where r is the radius.
As you can see, the diameter is 5 units, then the radius is:
The area of the figure is the sum of the area of the triangle and the area of the semicircle.
Then, the result is:
we know that
in the right triangle JKL
Because
and are complementary angles
so
therefore
