Answer 1

Area of the whole figure =  0.5m^2   ( half * base * heighT)
Area if the circle = pi r^2 = pi k^2

So area of shaded part =  0.5m^2 - k^2 pi 

Answer 2

Because we're looking for the area of the shaded region, we'll use the area formulas for the circle and triangle.

The shaded region is defined by the area inside the triangle, with the circle not being shaded. This means that you'll subtract the area of the circle from the total area of the triangle.

The radius of the circle is given by k. The base and height of the triangle are given by m. Write the formulas with these terms:

Circle:
$A = \pi k^{2}$

Triangle:
$A = \frac{m * m}{2} = \frac{m^{2}}{2}$

We are subtracting the area of a circle from the area of the triangle. The following equation is your answer:

$\frac{m^{2}}{2} - \pi k^{2}$
