As I said it was a quick sketch, the angle between the sides 7.6 and 7.2 worked out as 87 and the length 3.2 worked out at 3.206.

Worked out to about about 75m/2 in my head...order 80m/2 for wastage.

Based on the bottom horizontal at 7.2m + 2.6m & the vertical 7.6m gives you 75m2 so adding on the odd 'bits' at the top & bottom of the garden I'd be going towards the 90m2.
I'm with him^.

Having checked again, I'd be looking more towards 95m2. That little "square" on the bottom left is roughly 10m2 on it's own which gives 85m2 give or take, which leaves the triangle at the top.

What is the approximate angle between the 3.2 and 3.5m sides - knowing that would take a lot of the guesswork out.

With your exact address I can do it very accurately using promap. It uses ordnance survey data

No, what we need is a 5D BIM model.

I make it 75.1 sqM.

I know that isn't very helpful.

It's a new build estate - will this matter?

Apologies - it was dark when I got home last night so no further measurements.

I'm thinking if I order 80sq m I should be just about OK? or go for 90?

Well given the bottom dimension is 9.8m and one side is 7.6m giving an area of roughly 75m2, and you then have, what looks to be from the measurements, an area bottom right of roughly 7.5m2, plus the triangle at the top which is going to be around 9m2 (give or take since it's not to scale), I'm going to go with my original answer of 95m2 to be sure.

Just measure out the biggest rectangles you can and then add a bit for good measure.

A few trees, maybe a bush or two would certainly help!
