。
Is she around here somewhere?
Literal
She [topic-は] around-here [at-に] is [question-か]?
そこら ('around there, thereabouts') is the casual cousin of その辺 ('that area') — a vague locative covering 'somewhere in that vicinity'. The ら ending generalizes the demonstrative そこ ('there') into 'around there', loosely. Pairing it with the existence verb いる (for animate beings) and the question particle か gives a casual 'is she around?'. This is precisely the phrasing you'd use peeking around a room or office looking for someone. Note いる vs ある: いる for animate (people, animals), ある for inanimate (objects, abstract things) — a fundamental Japanese distinction that English lacks.
