How many square titles of side 20 cm will be needed to pave a footpath which is 2 meters wide
and surrounds a rectangular plot 40 m long and 22 m wide
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Calculate the area of the pave as the difference
(40+4)*(22+4) - 40*20 square meters
and then divide it by the area of one tile which is 0.2*0.2 = 0.04 square meters.
