19*1000*1000/(450*32) = 1319.44
You can't convert meters to square meters.
first lets convert m to mm.we know, 1 m=1000 mm. 5 m =5000 mm and 8m=8000mm. Now, no.of paving slab = area of flags /area of slab . =5000 X8000/450 x 450. =197.5 = 197 slabs.

A kilometer is one thousand (1000) meters. You would need to walk one thousand meters.

This question cannot be answered as it stands. Meters and square meters are different in that one is length and the other area. To answer this, you would need to specify the dimensions of the wood that you are using to cover the floor. If you are using 5cm wide strips of wood, then you would need 20m^2 / .05m = 400 linear meters of wood strips. Then add 10% for cuts,knots and mistakes.

To convert meters per second to kilometers per hour, multiply by 3.6.
The area of a rectangular deck is found by multiplying it's width and length. In this case, a 5.4 by 4 meter deck would require 21.6 square meters of material to cover. ------ The above is true but you asked about how many linear meters of decking you would need to cover this area. To answer this you would need to give us width dimension of the decking planks that you were thinking of using.
84 m2 of course !
The rate that you cover a distance is your speed. Speed is a measure of the distance traveled per unit time. If your units are meters and seconds, then your speed would be in meters/second. To find the speed of something you divide the distance it traveled by the time it took to travel that distance. For example if something traveled 40 meters in 10 seconds its speed would be (40 meters)/(10 seconds) = 4 meters/second
A car traveling 50 kilometers per hour would take 4.32 seconds to cover 60 meters.
