Answer:


\boxed{\sf (15)/(22) }

Explanation:

The radius of the circle is 7 cm.

The two legs of the triangles are 7cm as well.

Area of a trinagle is ( base × height )/2.


(7 * 7)/(2) =24.5

Multiply the value by 2 since there are two triangles.


24.5 * 2 = 49

Calculate the area of the circle.


\pi r^2

The radius is given.


\pi (7)^2

Take
\pi as
(22)/(7)


49((22)/(7) )


=154

Subtract the area of the two triangles from the area of the whole circle.


154-49=105

The area of the shaded part is 105 cm². The total area of the shape is 154cm².


(105)/(154) =(15)/(22)
