This question is too vague to have an answer, but here is one.
For the shaded area (pie wedge) of a circle, find the area of the circle and multiply by the ratio of the wedge angle to the entire circle (angle/360).
For the shaded region of a triangle, find the area of the smaller triangle, if necessary using trig functions to define a known angle or length of a side.
For other polygons, you may be able to divide the area into triangles separately, then sum their areas.

You will need to divide the shaded area into smaller parts, such as triangles or rectangles, or find the length of sides of these polygons.
The approximate area of the shaded region of 10 cm is 100 square centimeters.
Simply put, the area of a shaded region can be calculated using: Area of shaded region = Total area - Area of unshaded region. Sometimes finding the area is simple, and other times, not so easy. Often , it is necessary to subdivide areas into shapes mathematics provides regular area formulas for.
(pi * radius squared) * ( sector angle / 360 )
To find the area of the shaded part in a rectangle, you first find the total area of the rectangle by multiplying its length by its width. Then, you subtract the area of the non-shaded part from the total area to get the area of the shaded part. The formula would be: Area of shaded part = Total area of rectangle - Area of non-shaded part
