    Or a measuring tape, that would work as well.

    Make a right-angled triangle at either end.

    (80-70)/2 = 5.

    Use Pythagoras Theorem.

    34 squared = 5 squared + X squared

    1156 -25 = X squared

    X = square root of 1131

    X = 33.63 cm

    Nope.

    I googled it and got the answer. Still don't understand it though.

    I won't post the answer. I'll leave it for a while to see if some number freak gets it.
