The answer will depend on the width of the decking boards.
Lineal metres = Square metres/Width of the boards.
Lineal metres = Square metres/Width of the boards.
You need to know the width (in metres) of the decking. Then Linear (or lineal) Metres * Width = Square metres so Linear Metres = Square Metrage / Width
136x32x100 - the gap between the boards
Lineal metres = Square metre/Width = Square metres/0.14
156 meters squared = 24,336 meters.
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.
147.63
14400 lineal feet to square meters
16 meters
Actually, linear meters and meters are the same. So, you have 145,770 linear meters of timber.
Multiply feet by 0.3048
