Multiply them both, and you get 190 meters2.
1 km = 1,000 meters2 km = 2,000 meters3 km = 3,000 meters4 km = 4,000 meters4.5 km = 4,500 meters1 km = 1000 metres so 4.5 km = 4.5*1000 = 4500 metres. Simple!
If a square has a perimeter of 80 meters, then each side is 20 meters in length. (80/4 sides of a square=20) The area of a square is side2, so 20*20 equals 400. The area of a square that has a perimeter of 80 meters is 400 meters2.
The best-known system of units is the SI, so I'll use it as an example. SI has several "base units", like meter (for length), kilogram (for mass), and seconds (for time) (a total of 7 base units). Other units are derived from the seven base units; for example, areas are measured in meters2, volumes in meters3, speeds and velocities in meters/second, etc.

yes the area is 30 meters2 and the carpet is 5x5 meters which is 25 meters2 so it CAN fit. But I warn you, it will not be able to cover the whole floor.
