Answer:
we need 98 tiles
For 17 packages 4tiles will be left over.
Explanation:
for part 1
it is 7tiles long and 9tiles wide
total tiles needed=7*9=63tiles
for part 2
it ia 5tiles wide and 7 tiles long
total tiles needed=7*5=35
overall tiles needed=63+25=98
in 1 package we have 6 tiles
im 17 packages we get 6*17=102 tiles
left over tiles=total tiles-tiles needed
=102-98=4tiles
