Answer:

Step-by-step explanation:

the first figure is rectangle , so

length = 15cm, breadth = 6cm

therefore area = l * b = 15*6 = 90cm^2

second figure is also a rectangle so,

length = 12+6 =18 cm ( or 9+9) , breadth = 9cm

therefore area = l*b =18*9 = 162cm^2

third figure is a semicircle , so

d = 11+9 = 20 cm  , r = d/2 =20/2 =10cm

area of semicircle = [tex]1/2[/tex] * [tex]\pi * r^2\\[/tex]

=1/2*22/7 *10*10

=1100/7 = 157 1/7 cm^2

if you add all the areas then you will get the requires area

hope it helps you
