Answer:
Complex sentence
Explanation:
A "complex sentence" contains one independent clause and one or more dependent clauses. It uses a "subordinating conjunction" like the following: after, although, because, as soon as, until, when, whenever, even though, unless, etc.
The sentence above is composed of one dependent clause: "After going to the beach with her friends" ⇒ It uses the subordinating conjunction "After"
The sentence also consists of one independent clause: "Samia went to the coffeeshop."
Thus, the sentence is a "complex sentence."
