Answer:
20
Step-by-step explanation:
first find the are of the entire rectangle
6×4= 24
then find the one of the white one
2×2= 4
subtract the 4 from 24
24-4=20
We can not evaluate it with real numbers, because there is no real number that multiplies itself twice and gives -25.
The answer is an imaginary number.
√-25 = 5i where i = √-1
So it can only be computed using imaginary numbers.
