Am trying to help my autistic son with his review and one of the question is as per the attachment. I uploaded a .gif version of the question because am not sure whether I can enter the question here properly.
The question goes as below:
The length of the diagonal of the base of the container is d metres.
Show that the height is given by
I do not know whether am trying to solve the problem correctly or not. I tried to solve the problem the only way I know how which is using Pythagoras Theorem and doing
d^2 = (2h+1)^2 + (h+3)^2
And am stucked at
d^2 = 5h^2 + 10h + 10
Can anyone please advise whether am trying to solve this problem correctly or not. Any advise much appreciated. For the meantime, I'll try Google and see if I can find a similar question.
Thanks in advance.
