Answer:
8 unit ^2 or 8cm^2
Step-by-step explanation:
area 1
1/2 ( 3 x 3 ) = 4.5 unit ^2
area 2 we split the triangle into half
= 1/2 ( 2 x 2) = 2 unit ^2
we know the other half is also 2 unit ^2 but we add then subtract
1/2 (1 x 1) = 0.5^2
To get
4.5 + 2+ 2 - ( 0.5) = 8 unit ^2
From the plot, we see that
. Its conjugate would be
, so that the product of the two is

More generally, note that if
, then
