9300 is the correct answer
We draw complex numbers as points, where the x,y coordinates are the real and imaginary part:
So, we have
So, both 
and 
are represented by the point (1,1).
Their product is
And its representation is
Answer:

A geometric proof involves writing reasoned, logical explanations that use definitions, axioms, postulates, and previously proved theorems to arrive at a conclusion about a geometric statement.
It's just a tiny bit sloppy. The 10.2 cm should be designated with a right angle too. I'll answer it that way.
Area = (L1 + L2)*h/2
L1 = 10.2
L2 = 12.2
h = 12.6
all givens are in cm.
Area = (10.2 + 12.2)*12.6/2
Area = 22.4 * 6.3
Area = 78.12 cm^2
