How to solve this prob

Can u pls give a hint as to what i have to do to solve the problem…

Hey @code_breaker-1001 We have to find a recursive relation to tile a floor of size M x N given tile size is 1 x M
When you keep the tile vertically, number of ways of tiling the remaining floor is f(n-1) as n-1 is the remaining width.
When you keep the tiles horizontally, number of ways of tiling remaining floor is f(n-m).
So total number of ways of tiling is the sum of both.
