Question 894333: A rectangle ABCD, which is 40 inches high by 20 wide, leans so that its top is 4 inches to the right of vertical.
ie corner A (top left) is 4 inches to the right of corner D (bottom left).
By how much must I lift corner C to make the sides AD and BC vertical?
(and how do you work it out accurately?)
The answer will be about 2 inches but that's logic, not maths.

Question 894378: The area of a rectangle is 72 centimeters^2. What is the value of n if the length is n+9 and the width is .4?
I've tried and gotten two complete different answers and when checked they aren't even close to the answer. I've tried 72=n+9/.4 and got 19.18 which when checked using the original formula i got 16.92 and that is nothing close to 72. I tried doing it like this 72=.4(n+9) and got 62.6 and when checked i got 34.04 which is also not correct. I need help soon. I've asked friends also and their methods don't work.
