1.) combination of a traingle and a semicircle(radius is 7cm and height is 15cm)
2.)combination of a rectangle and 2 semicircles(witdh in rectangle is 7m and the lenght in rectangle also is 20m)
pls do give answer fast as i need it quick and no spam pls

Step-by-step explanation:
Solution:
Given that:
Height of the rectangle =h
Base of the rectangle =3h
To find:
Area of the figure =?
Solution:
Base of the rectangle= Diameter of the semicircle
∴ Radius of the circle =6h
Now,
Area of the figure = Area of the rectangular part + Area of the semicircular part
=h×3h+21×π×(6h)2
=3h2+72πh2
=(7224+π)h2
