Question: How many games do team in the league where Barcelona won titles in 1948 and 1949 play?

Knowledge 1: FC Barcelona
After the construction was complete there was no further room for expansion at Les Corts. Back-to-back La Liga titles in 1948 and 1949 and the signing of László Kubala in June 1950, who would later go on to score 196 goals in 256 matches, drew larger crowds to the games. The club began to make plans for a new stadium. The building of Camp Nou commenced on 28 March 1954, before a crowd of 60,000 Barça fans. The first stone of the future stadium was laid in place under the auspices of Governor Felipe Acedo Colunga and with the blessing of Archbishop of Barcelona Gregorio Modrego. Construction took three years and ended on 24 September 1957 with a final cost of 288 million pesetas, 336% over budget. [SEP] Knowledge 2: La Liga
The competition format follows the usual double round - robin format. During the course of a season, which lasts from August to May, each club plays every other club twice, once at home and once away, for 38 matchdays. Teams receive three points for a win, one point for a draw, and no points for a loss. Teams are ranked by total points, with the highest - ranked club at the end of the season crowned champion.

A total of 62 teams have competed in La Liga since its inception. Nine teams have been crowned champions, with Real Madrid winning the title a record 33 times and Barcelona 25 times. After Athletic Bilbao claimed several titles in the league's early years, Real Madrid dominated the championship from the 1950s through to the 1980s, when Athletic and neighbours Real Sociedad each won the league twice. From the 1990s onwards, Barcelona (15 titles) and Real Madrid (9 titles) were both prominent, though La Liga also saw other champions, including Atlético Madrid, Valencia, and Deportivo de La Coruña. In the 2010s, Atlético Madrid became increasingly strong, forming a trio alongside Real Madrid and Barcelona which occupied the podium places exclusively.
