# Count 'em All 8!

Count the number of $$3\times6$$ rectangles in the $$50\times39$$ grid above.

I'm lazy to draw new grids by the way.

Details and assumptions:

• Dimensions are expressed as width$$\times$$height. Thus a $$3\times6$$ rectangle (that is, a rectangle of width 3 and height 6) is considered to be different to a $$6\times3$$ (width 6 height 3) rectangle, in this case, you only want the $$3\times6$$ rectangles, not the $$6\times3$$ ones.
