what is the Sq m of this plot?

CamperMan

OK a plot of land, kind of cone shaped, 13 m at one end, 19 m at the other and 117 m long, what is the total Sq m of this area?

Thanks

Can you clarify the exact shape? Are you talking about a trapezium



by any chance?

If so the area is just the average of the two sides multiplied by the height, i.e.

[latex] \displaystyle \frac{a+b}{2} \times h [/latex]

this is the shape

Yep, that's a trapezium with:

a = 19 m
b = 13 m
h = 117 m

so the area would be:

[latex] \displaystyle \frac{a+b}{2}\times h = \frac{19+13}{2}\times 117 = 1, 872\hbox{ m}^2[/latex]

i.e. nearly half an acre in old money.

I probably should have explained the trapezium shape a bit better. The two sides shown in my last post can be any angle - all you need for a trapezium is two parallel lines (the top and bottom in the pic), and then two straight lines to complete the shape (quadrilateral).

thanks Michael!

No bother at all.
