Ok thanks! In the google translate this phrases sound alike.

No, they don't sound alike. The "a" in mansion does not sound close to the "e" in dimension. On the other hand, in some dialects of English, a "di" is spoken instead of "the." You can hear how many words are pronounced, both in American and British English, at thefreedictionary.com Click on the icons of the loudspeaker, and on the American and British flags. Try these two: There was sun on the beach. (Había sol en la playa.) There was a son of a bitch. (Había un hijo de p...). [I don't ordinarily talk this way, but after all, we are learning languages here.]
