<span>If the width is w, and the length is w+10, then the perimeter is
2w+2(w+10),
If that is the case you need
4w+20-4,or 4w+16 tiles </span>
Answer: 72
Step-by-step explanation: Its in the middle
If 10% was added to the total (100%), then subtract 10% from 17.85.
17.85 * 0.1 = 1.785
17.85 - 1.785 = 16.065
$16.07
1/7 = 0.14285714
rounded to the nearest thousandth, it would be 0.143
