To add complex numbers, it is necessary to group the similar terms (real and real, then imaginary and imaginary) before simplifying. This will be done as follows:
(-4 + i) + (10 - 5i)
Grouping similar terms:
(-4 + 10) + (i - 5i)
6 - 4i
From the choices, the correct answer is C.
Here,
In Right angle triangle,
base = 12 m
height = 8 m
Now,
◇ Area = 1/2*b*h
= 1/2*12*8
= 48 m^2
In semicircle,
radius = 4 m
Then,
◇Area" = 1/2*22/7*r^
= 1/2*22/7*4*4
= 25.14m^2
Again,
◆Total Area = Right triangle + semicircle
= (48+25.14) m^2
= 73.14 m^2
This is right answer...
