Can someone help with 11 part (ii) and (iii) and 12 part (iii)
On part 2 I got to the step of 0.5 x root 160 x root 40.
Does it expect us to do this, or is there a simpler way of approaching? I just did the long way lol of working out the square root of 1600 which is 40..
And I have no idea what to do for (iii) Once I can get the first step of proving it I can do the rest.
Oh and when the questions say show that the equation of blah blah blah has only one real root. Is that just asking b^2 - 4ac = 0 ?

For 11 part two, it's best to draw a diagram and then join the points up
Find the heigh and times this by the length and divide by 2
Sorry, haven't got time to do the rest
I've got an exam in an hour 😂
