Please help solve a math question

[WorraLiberty]

I want to cover 97.5 square meters of garden in decking tiles.

Each tile measures 30 x 30cm.

How many tiles do I need please before I throw the bastard calculator at the cat and burn the fucking garden? 😐

Got any graph paper? DH got 14* different results using various calculators when we turfed the lawn, I was closest with my diagram.

(* I may have exaggerated slightly for effect)

Are you sure you've calculated the square meterage correctly as that is a large area and you'd need 1083+ tiles?

What number are you getting? As pp I would suggest sketching. I’m getting about 1000 tiles (give or take 20 or so) but that doesn’t feel right.

And that’s why it doesn’t feel right! It is a big area for quite small tiles.

Does your garden area measure roughly 10m by roughly 10m? That's quite a large area for decking. Did you measure right?

1083 tiles.

How good are you at cutting tiles?
What are the actual dimensions of the area you want to cover?

1083 as a minimium. More, depending on how the tiles fit the dimensions, and how many tiles cut neatly, and how many cut parts you can use elsewhere.

What's the length and width of the area?

100 square metres? In decking? That's bigger than my two bed two bath large terraced flat!

But yes
97.5m / (0.3m*0.3m) = 1,083.3333333333 tiles
So 1084

Jeez - how much is each tile?

Reconsidering yet Worra?

Sorry to derail, but I am confusing myself.....

How can 0.3m x 0.3m be 0.09m squared? I understand that area equals length times width, but how does it work when multiplying numbers less than 1??

Oh bloody hell I think I've clearly made a massive mistake! 🤭😂😂

The garden is 48 feet long and 25 feet wide if that helps

My two-storey, three-bedroom semi-detached house is 101m2.... That’s going to be a huge deck!

Yeah just a bit 🙈 😂

48 x 25 feet is still a massive amount to deck! Are you decking the whole garden?!

@HarrietLong you are multiplying to decimals.
So try to think of it multiplying like this...
Starting number X number bigger than one. Answer is bigger
Starting number X 1. Answer is equal to starting number.
Starting number X number smaller than one. Answer is smaller than starting number.

So, you want a deck 14.63m by 7.62m?? I make that 111.48m2....

Anyway, assuming you cant reuse cut tiles, you need 48.7 tiles across, and 25.4 tiles back.
49x26= 1274 tiles, plus some spares for mistakes.

Yes more or less.

We were going to lay patio slabs because the dogs have ruined the lawn but we thought it might be cheaper/easier with composite decking tiles.

@HarrietLong also.
Think of 0.3 as 3 / 10.
So
0.3 X 0.3 is the same as
(3 / 10) X (3 / 10)
0r
(3 X 3)/ (10x10)
So
9/100 = 0.09.

There's loads of YouTube videos that will explain it better than that though

Thank you

That's a massive area. Either decrease the area by adding something else or get bigger tiles. With your numbers, 111.5 (leaving room for error) divided by 0.09 is 1238 tiles.

30cmx30cm is approx 1ft2 so you'd need 48x25 = 1,200. Roughly.

B&Q says you need 1363 (your garden is 14.63m by 7.62m, which is insanely big - are you sure that's right?)

There has surely got to be a better solution than covering the whole garden in plastic?
