This study attempts to tentatively focus in on the association between Saudi Arabia's GDP and extension rate from 1969 to 2020. To connect GDP and extension rate, the audit used different econometric models, including Typically Least Square (OLS). The unit root test (ADF test) and conventionality tests (Jarque-Bera) use to assert the precision of the data in this audit. The audit makes sense of a couple of composing studies in which clever assessment papers are alluded to in various parts and sections of the survey, in this way focusing research openings and allowing the assessment to proceed. Using the OLS model, the results uncover no gigantic relationship among Total national output and development rate in Saudi Arabia all through the period analyzed.
