Very interesting question!

But, √-4 is not a real number; in fact, the result of √-4 is 2i.

The i is an imaginary number and it basically is a solution for √-1

(So, i^2 is = -1).

Since -4 is negative, the square root doesn't exist (in terms of real numbers) just because you can't multiply any two identical numbers to get a negative result.

-2 x -2 = +4
2 x 2 = +4

That is why √-4 is NOT considered a real number.

Hope I could help you out!
Have a good one, and God bless!

Answer:

4448 feet²

Step-by-step explanation:

Using the formula $A = 2((l)x(w) + (l)x(h) + (w)x(h))$ we can take the length, width and height and plug them in. $A = 2(44x21 + 44x20 + 21x20)$ , solving this equation we get $4448 feet^{2}$ .
