Answer:
4 weeks and 2 days
Step-by-step explanation:
There are 7 days in one week.
To convert 30 days into weeks and days, divide 30 by 7.
The biggest number you can divide it by is 4 [without going over 30]
7 x 4 = 28.
30 - 28 = 2.
So 30 days = 4 weeks and 2 days.

w - width
2w + 5 - length
w + w + (2w + 5) + (2w + 5) = 6w + 10 - perimeter
34 cm - perimeter
The equation:
6w + 10 = 34 <em>subtract 10 from both sides</em>
6w = 24 <em>divide both sides by 6</em>
w = 4 cm
2w + 5 = 2(4) + 5 = 8 + 5 = 13 cm
<h3>Answer: Width = 4cm, Length = 13cm</h3>
