You need to fill up this section properly. The equations you provided aren't particularly useful because the first one refers to an infinite line of charge, the 2nd one is for an infinite plane of charge. You have to integrate over the length of one of those lines of charge. Then you can use the result for the other two lines of charge to get the answer. Now, how would you set up such an integration?
