Umm... 178.2 x 0.09 ≠ 1980wat did every get for that tile one the last one how does it equal 1980 and something about 10 percent extra for breakage my equation was...
178.2 x 0.09 = 1980 ....i was so glad that i got it rite 2 marks in the bag
the area of the rectangle is 162 +10%[16.2]=178.2 and the tile is 0.09^2
so ye i just did 178.2 x 0.08 = 1980 soo happpy
I done:
162 x 1.1 = 178.2
178.2 / 0.09 = 1980
