I've shortened the advice, as there were lots of statements repeated, for exampe giving the formula for the area, then justifying it with a diagram, and then giving the formula again. Fixed typos and reworded the questions to remove duplication of "the following..." in the statement and parts.

Nice question. However, "a trapezium can be interpreted as half of a parallelogram, this is shown below", isn't really shown below. Since you have included the graphic of the parallelogram, I think that you need to be consistent, and include something along the lines of this: http://www.mathguide.com/lessons/picdemotrapezoid.gif

Hey Aiden,
I haven't noticed Chris has already made this suggestion when I started fixing part a) for you so you could see how to fix other parts. I've done it, so part a) should now work. Don't forget to put everything in one line before you do the conditional visibility.
There was one problem I came across. Sometimes, even when wh00 = wh00dp was true, Numbas thought it was false. When I made wh00 round to 2 decimal places (so practically stay the same as it already was), this problem seems to have vanished so I advise doing the same for other parts. It is some kind of an error.
Chris Graham 3 years, 8 months ago
Aiden, is it just the conditional visibility which doesn't work? If so you could put 2 versions of the whole equation into different blocks: one for
wh00 = wh00dp
and one forwh00 <> wh00dp
.

Saved a checkpoint:
Why do I need to round my answer at all?
I agree with Vicky and Hannah's suggestions.
Vicky Hall 3 years, 8 months ago
In parts a) and b), sometimes the answer is already an integer and doesn't need to be rounded so you end up with two identical lines in the advice. (Also, part a) doesn't round at all even when it should do so that needs to be fixed.) You can code your advice section so that certain lines only show if the solution does need to be rounded (I would speak to Lauren about it if you're not sure how as she has an example of this in one of her questions).
I have reworded part a) slightly to make it more succinct and I have also put the unit $\mathrm{m}$ into \mathrm. Have a look through the other parts and try to reword a bit more clearly. I agree with Hannah's advice:
\[\text{I think you need to start the advice for each part with 'The area of a parallelogram is calculated using the formula...'}\].

Hannah Aldous 3 years, 8 months ago
part a says round to 1 dp but only marked correct 2 dps
not sure how easy this is to do but on the trapezium diagram could you line up your values for the number on top and bottom
in part d, a + b needs to be in LaTeX
in your advice you've put m for metres in LaTeX for several of the answers but not all
I think you need to start the advice for each part with 'The area of a parallelogram is calculated using the formula...' instead of 'Paralellogram:'
you've put the word height in LaTeX in part c
in part d I would write 'half of a' instead of 'half a'
typo 'interpretted'
you have a space before a comma in part d
you've written 'this is shown below' but haven't shown below.

Where it says shown below. I am hoping to insert GIFs of the explanation above. I am going to do this over the weekend; if it works i'll insert it if not I will omit the line and gap.

These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
