Derived units are the units which are derived from the fundamental units.
Area of rectangle = length×breadth
SI unit of length = m
SI unit of breadth = m
Unit of area = m×m = m²
Dimensional formula = [M^0 L^2 T^0]
speed = distance/time
SI unit of distance = m
SI unit of time = s
Unit of area = m/s
Dimensional formula = [M^0 L^1 T^(-1)]

These are derived from fundamental units
Area of rect=l*b
Speed=dist/time
