Answer:
Lenght of a rectangle = 20cm
Breadth of a rectangle = 14cm
Area of a rectangle PQRS = l*b = 20cm*14cm = 280cm^2
Diameter of a semicircle = 14cm
Radius of a semicircle = 14/2 = 7cm
Area of a semicircle = πr^2/2 = 22/7*7*7/2 = 77cm^2
Area of the figure = Area of a rectangle PQRS + Area of a semicircle
= 280cm^2 + 77cm^2
= 357cm^2
