half base x height = 450mm (0.45m) x 900mm (0.9m) = 0.405m2

yup, for a non riht angle triangle u'll have to draw a line down the middle, then work out the length of the middle line using pythagoras (A squared x B squared = C squared)

then one u have that then u can half the base and multiply by the height of the new middle line then thats it

i bet ive confused u now like

yeah, if u draw a line thru ur equalatral triangle it will two right angles.
and u could rearrange em has a rectangle, so u don't need to divide by two

pythagoras therom only works on right angled triangles to find the hypotemeus (longest side) or can use the old SOH-CAH-TOA

yeh and when u draw a middle line through the tringle u have 2 right angled triangles, so u use pythagoras on one of the halves to find out the length of the middle line.
