Rachel needs 1776 inches of board
<em><u>Solution:</u></em>
Given that, Rachel is making a planter box
Her box measures 345 inches long and 543 inches wide
Length = 345 inches
Width = 543 inches
<em><u>To find: Inches of board she needs</u></em>
So we need to find the perimeter of the board
The board is usually of rectangular shape
<em><u>Perimeter of rectangle is given as:</u></em>
Perimeter = 2(length + width)
Perimeter = 2(345 + 543)
Perimeter = 2(888)
Perimeter = 1776
Thus she needs 1776 inches of board
The total length of wall is 160 inches
<em><u>Solution:</u></em>
Given that,

1 feet = 12 inches
Therefore,

There are 20 bricks lined up end to end to make the wall
<em><u>To find: Total length of wall in inches</u></em>

Thus we get,

Thus total length of wall is 160 inches
Answer:
Mean: How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
Step-by-step explanation:
Therefore the mean is: 4
how?
2+4+4+6= 16
then we would find how many values are there, which is 4
so 16 divided by 4 is 4
Hope this helps!
