In this paper, we have investigated five dimensional plane symmetric cosmological model in the frame of scalar field in
presence of binary mixture of perfect fluid and dark energy given by cosmological constant. The perfect fluid is chosen to be one
obeying equation of state P = γρ with γ ∈ [0,1]. The exact solution of Einstein’s field equation are obtained corresponding to
higher dimensional plane symmetric cosmological model. Models with power-law and exponential expansion have discussed in
detail.
