Math Problem Statement
Solution
The problem describes a triangle with sides , , and . Each side is the diameter of a semicircle, and the shaded areas , , and correspond to these semicircles. The question asks for , where , , and are the areas of the grey semicircles as shown in the diagram.
Step 1: Area of a semicircle
The area of a semicircle is given by: where is the radius of the circle, which is half the diameter.
Step 2: Calculate the areas , , and
The diameters of the semicircles are the sides of the triangle.
