Hello Divya. The dimensional analysis makes use of dimensions and the dimensional formula and based on the physics laws and the principle of homogeneity. In simple words, while solving physics problems, you will have to determine the numerical value and the units of a variable. Determining a unit of the variable is not an easy task. For this purpose we use dimensional analysis method.

Divya, dimensional analysis is not just used for determining the unit of a variable in an equation, but also helps in checking the consistency of an equation. I.e. All the physical equations should be consistent. But the reverse may not be same.
F = m2× a
F = m × a2 i.e L.H.S. ≠ Dimensions of the R.H.S.
