if you mean both dimensions are complex numbers, then you use foil.
Example
(1+i)(1+2i)= 1 + 3i - 2 (since i2 = -1)
-1+3i
that's a rectangle but you should understand if your in a class with complex #

How do you find square root of a complex number?
This is best done if the complex number is in polar coordinates - that is, a distance from the origin, and an angle. Take the square root of the argument (the absolute value) of the complex number; and half the angle.
How do you find the perimeter and area for complex shapes without a grid?
To find the perimeter and areas of complex shape without a grid you should divide the shape into simple shapes and find the area of each shape alone and then add up the areas all together to get the area of the whole shape. Example: If there is a shape that can be divided into 2 triangles and 1 rectangle then you will find the area of each triangle alone and then the area of the rectangle then add up all the areas together.
What is the need for complex numbers?
The square of any real number cannot be negative. However, there are equations whose solutions require the square root of negative numbers. The real number system was extended to the set of complex number to allow such operations. In some ways, this is analogous to the set of integers being extended to the set of rational numbers to allow division (when the denominator was not a factor of the numerator), or the set of rational numbers being extended to real numbers to allow square (and other) roots.
How do you find out the domain of x squared?
You can square any real number (complex ones too) so the domain is all real numbers.
Explain why it is not possible to take a square root of a negative number?
Actually, it is. It just depends within what set you are doing your calculation, that is, what do you consider an "acceptable solution". The question of the square root means, which number, when squared, gives a specific number. Within the real numbers, the square of a positive number is positive, the square of a negative number is also positive. Therefore, there are no real numbers whose square is negative. Within the complex numbers, the square root of -1, for example, is i (the "imaginary unit") - that is, i2 = -1. Similarly, the square root of -4 is 2i, the square root of -9 is 3i, the square root of -2 is (square root of 2 times i), etc. In some areas, complex numbers are acceptable as solutions, in other areas, they are not. In the same vein, negative numbers are acceptable as solutions to certain problems, but not for certain other problems.

What is the area of a complex figure with a perimeter of 112 feet?
Anywhere between 0 square feet and approx 998.2 square feet - it all depends upon the exact shape of the complex figure. To calculate the area of a complex figure, split it up into shapes for which you can workout the area and then add all the areas of the shapes together.
When was Dzanga-Sangha Complex of Protected Areas created?
Dzanga-Sangha Complex of Protected Areas was created in 1990.
How many square feet is a 10 x10 feet room?
The floor and ceiling each have areas of 100 square feet. In order to find the areas of the walls, we need to know the height of the ceiling.

What is the correct notation for the complex number square -81-14?
-81-14 is not a complex number. And its square is 9025.
Can anybody help me with this discrete mathmathic problem I can't find the right answer?
Start with a square that has sides of length 1. Join the midpoints of the sides of the square to form a second square inside the first. Then join the midpoints of the sides of the second square to form a third square, and so on (as shown). Determine the sum of the a. areas of the infinite number of squares b. perimeters of the infinite number of squares. how do you find the calculate an accurate sum of perimeter and areas of square when they are infinite number of square..... I only can find the formula ..
Find all the real square roots of 0.004?
( +0.063246 ) and ( -0.063246 ).These numbers are rounded.These are the only square roots of 0.004. There are no more real ones,and no imaginary or complex ones.
What is the absolute value of a complex number?
The absolute value of a complex number a+bi is the square root of (a2+b2). For example, the absolute value of 4+9i is the square root of (42 + 92) which is the square root of 97 which is about 9.8489 (The absolute value of a complex number is not complex.)
What is the area of Cheddar Complex?
The area of Cheddar Complex is 4,413,000.0 square meters.
