The aim of the paper is to introduce the spaces ℓ∞λ(\widehatF) and ℓpλ(\widehatF) derived by the composition of the two infinite matrices Λ=(λnk) and \widehatF=( fnk ), which are the BK-spaces of non-absolute type and also derive some inclusion relations. Further, we determine the α-, β-, γ-duals of those spaces and also construct the basis for ℓpλ(\widehatF). Additionally, we characterize some matrix classes on the spaces ℓ∞λ(\widehatF) and ℓpλ(\widehatF). We also investigate some geometric properties concerning Banach-Saks type p. Here we characterize the subclasses K(X:Y) of compact operators, where X∈\ℓ∞λ(\widehatF),ℓpλ(\widehatF)\ and Y∈\c0,c, ℓ∞, ℓ1, bv\ by applying the Hausdorff measure of non-compactness, and 1≤ p
