If my pool measures 16.0m x 10.0m and i want to put a tiled path 2.0m wide around the perimeter of the pool, (tiles are 2.0m squared), how many tiles do I need to buy?

The easiest way to solve this is to draw a rectangle and then draw the 2m of tiles around the outer edge. Now find the new total width and height.
(2m extended on each side would give you dimensions of 20 x 14.) Get the total square meters of these new dimensions and you will have 280 square meters.
Your original pool was 16 x 10 or 160 square meters.
Subtract the difference (280-160) and you have 120 square meters of area covered by tiles.
Each tile is 2m squared of 2m x 2m = 4 m
Divide 4m into 120 square meters and you will find you need a total of 30 Tiles to build a path around the perimeter of your pool.

There are two sides of length 16, which need 16/2 = 8 tiles along each. Then there are two sides of length 10, which need 10/2 = 5 tiles along each. So that gives you 8 + 8 + 5 + 5 = 26 tiles to go along the sides. However, to complete the path, you need a tile in each of the four corners. So the total number fo tiles is 26+4 = 30.

You should have told us the SHAPE of your pool. Assuming that your pool is rectangular, then you would need 8 tiles on each side and 5 tiles on each and 1 tile each corner for a total of 30.

For the long axes, you will need 8 + 2 = 10 per side
and for the short axes, 5 per side
Why? Draw a picture: the long axis is 16 m long, each tile is 2 m square, 16/2 = 8 plus the two at the ends or 10 per long axis; the short axes need 10/2 = 5 per side
Total tiles (10/long axis/side)(2 sides) + (2sides)(5/short axis/side) = 20 + 10 = 30

You just use the perimeter formula of finding the perimeter of a rectangle and then divide it by the tile's lenght
Which will give you 26 tiles

20x2=40
14x2=28
68\2= 32
32 tiles
