Remember:

A unit square has sides 1 unit long and an area of 1 square unit.
Area is measured in square units such as sq cm, sq in, sq ft and sq m.
Area of a rectangle = length times width, which is rows times columns.
A rectangle can be split into parts, and the whole area is the sum of the part areas.
To find the area of an L-shape, split it into rectangles and add their areas.
