Answer:
Part 1) The area of the shaded region is 
Part 2) The area of the shaded region is 
Step-by-step explanation:
Part 1) Figure N 1
I assume that the figure ABCD is a square
we know that
The area of the shaded region is equal to the area of the square ABCD minus the area of semicircle BC plus the area of semicircle AD
therefore
The area of the shaded region is equal to the area of the square ABCD
The area of the square is

Part 2) Figure N 2
I assume that the triangle ABC is a right isosceles triangle
so
AB=BC
AB ⊥ BC
The area of the shaded region is equal to the area of triangle plus the area of semicircle
A) <em>Find the area of the triangle ABC</em>
The area of triangle is

substitute


B) Find the area of semicircle
The area of semicircle is equal to

we have
-----> the radius is half the diameter
substitute


therefore
The area of the figure is equal to
