Answer:
Step-by-step explanation:
The triangle is an equilateral triangle with side=28 cm and the diameter of the semi circle is the side of an equilateral triangle, therefore, AB=28 cm
Now, Perimeter of the shaded region= Perimeter of Equilateral triangle+ Perimeter of Semicircle
=
=
=
=
Also, Area of the shaded region=Area of the triangle+ Area of the semicircle
=
=
=
=
