the concept of raster

each raster consists of cells which are rectangle. the area of a rectangle = length * width

so the area of a cell = length * width = X * Y

you have 5 classes, in the table of content of the raster you have, it has been determined that every class has how many cell in there = Count

so, if you multiply Count of cells in each class in Area of the cell you will have AREA,

note that, the x and y are in meters or centimeter in order to correct calculating
