    Calculate the value of OK.

    I think I know how to solve it, but I don't know if they put the 12.75 in there to trick me or if I'm actually supposed to use it in my equation.

    yes, 12.75 is just there to trick u

    Do I use 12.75 to set up a proportion for the two areas, though (which solving would be more difficult in my opinion), or should I simply set up a proportion for 17 and 4 to figure out the length of OK

    So...my proportion should look like this: 17/4 = OK/2

    assuming the trapezoids are similar, u can setup a proportion of corresponding sides

    \(\large \frac{OK}{2} = \frac{17}{4}\)
