This layout is easy for any person who likes to heavily storm on one side on the field and have little pieces fighting on other corners of weak parts. Also good for bases whose defence structures are near the edge of the walls. Some downsides to this the strategy is only a single Mortar must be available to fight or better, no Mortar.
Begin with using your Lightning Spell. If you have 2, only use one. The second one comes for worst case scenario. They should be used only for the highest priority building, the Mortar.
Next comes any area splash damage building and everything else. Swarm in on the nearest route next to the Mortar with Wall Breakers and Giants. Have Archers take out defensive structures where only that defensive structure can attack it. I normally use 10-15 Archers.
Later, your Giants will leave a huge crater in its path; follow up with Archers on the weak spot. Once you have destroyed every defence structure (except the Walls), send in 5 Goblins. If you're running out of time, send in more Goblins and Archers if that doesn't do the trick.
