Go 7 units of distance in any direction. Turn 90 degrees clockwise and go 7 units of distance in a straight line. Turn 90 degrees clockwise and go 7 units of distance in a straight line. Turn 90 degrees clockwise and go 7 units of distance in a straight line.

You will have travelled along a square route whose total distance is 28 units. Alternatively you could have turned counter clockwise each time.

the square root of -28 is the square root of -1 time the square root of 28. The square root of -1 is not a real number, it is represented by i. The square root of 28 is the square root of 4 times the square root of 7 (4*7=28) The square root 4 is equal to 2, and the square root of 7 cannot be simplified.

The answer is 2i√7.
