Calculate the area of this shape

[Dan_1981]

Rough idea of the area of this shape?

Apologies.

Awful drawing & not to scale

Sorry, can't help on the area, without a bit of scale correction.

Pretty much impossible from that drawing as you can't tell what is level with what. The easier way is to break the whole area down into smaller shapes that you can calculate (rectangles and triangles) and then add the sum together.

About 90m2

Hmmm didn't think it's be too easy.

It's our garden.

The the 7.2m & 7.6m are straight.

The 8.2 curves very slightly around

The 3.2 & 3.5 are straight.

[hurstg01]

depends on your definition of 'rough' - a guesstimate would be in the region like 60 sq m +/- 5sq m;

"About two-and-a-bit"

That was the stock answer during my A-level days, 38 years ago, and still holds good today when you take into account the variability of "a bit"!

How accurate an answer do you need OP???

I'll be ordering turf to lay this weekend - so will likely round up anyway.

[Trophy Husband]

72 m2 +/-5m2.

Though could pull the shape around to get pretty much anything! Perhaps should have set units to meters, as well!

I'll stick to approx 90.

Break into chunks.

There's the 7.6 x 7.2 rectangle = c55m2
The little bit bottom right is about 7m2
The bit left on the right side is about 16
The remainder at the top is about 12

ETA - diagram above makes the top bit a lot smaller, and reduces the right so maybe c75m2

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.

If turf, is it not better to just count the number of widths, then add up the total length? For turf, surely 1m squared area can't be filled by reusing a 10cm strip 10m long, the grass will just die.

A quick sketch out on autocad gives you 71.981 sqm with a perimeter of 38.7m

Had a quick look, I need another dim, from the top of 7.6m to the top of 8.6m, to get the angles right across the top.

[Dan_1981]

I can sort additional measurements this evening folks.

[Clive-sz8cz]

Drew it up using Microstation and I get an area of 71.22 sq.m. I assumed the 7.6 and 3.8m sides are parallel to each other and right-angled to the 7.2m side. Need some angles to do a proper job!

Anybody need any exhibition/event plans drawn up?

Im getting about the same, 72m2

Anyone interested in how youd draw this up, you use circles in autocad and a bit of guess work.

It can, actually. It's as tough as old boots provided it gets regulat water while sorting its life out. This summer I dug up some turf from one bit of the garden and used it to fill in an old flower bed. I used all manner of odd shapes and just stamped them into place. It all worked. The biggest proglem was that the joins tend to shrink a bit so you get gaps that you need to fill with earth. Passing animals, I suspect squirrels, have dug out some of the softer bits. But nothing's died and it's become a very lively bit of lumpy turf.

Without knowing the angles, or a few extra distances across the space so you build the whole shape out of triangles, you can't determine the shape precisely, so quoting an area to 5sf is dissapearing into spurious precision.

Given the info we've got, I'd say 71 +/- 6 m^2
