yehh that is what i got too. i'm pretty sure it's right? well i hope so!Question 23cii), did anyone else do it like this..?
i) Find the area of the terrace.
...... = 13.77m2
ii) Tiles are sold in boxes. Each box holds one square metre of tiles and costs $55. When buying the tiles, 10% more tiles are needed, due to cutting and wastage.
Find the total cost of the boxes of tiles required for the terrace.
So you go 13.77 + 10/100x13.77 = 15.147m2.
So this means that they need 16 boxes, not 15, as it's more than 15 and they can't buy part of a box.
Am i correct..?</SPAN>
