    Thats the question, it's on plans evaluation.

    It's asking me to fill in the missing measurments for the plan and side? What missing measurments? I just don't get it

    Please help.

    I think you just have to divide everything you see by 10...

    Hey thanksfor responding,

    I don't see a 40 there? Could oyu please tell me where you got the 4 from? I don't understand. Also the 6 and 6 bit was wrong - I just marked it, I understand the 14 and the 8 though. Thanks.

    4 is from 120-80 as the altitude is 120 and the side is 80 high so the difference is asked. And I'm sorry for the 6 as I made it wrong, it's 4.5 because it's 90/2 twice. Hope you understand now.

    No, you do NOT divide by 10. The measurements are given in "true" measurements, not the scale drawing and the "missing mesurements" boxes should be given the same way.
