Yes liquids and gases both exerts pressure and pressure exert by these two is called pressure due to fluids.
Which is given by:
$P = h ρ g w h e r e h i s t h e h e i g h t o f f l u i d ρ i s t h e d e n s i t y o f f u i d g i s t h e a c c e l e r a t i o n d u e t o g r a v i t y . S o p r e s s u r e d o e s n o t d e p e n d o n t h e a r e a .$
