Find the length of each side of the polygon for the given perimeter.

As the picture highlights, the opposite sides have the same lengths. The perimeter is the sum of all lengths, so we have

Plug the required value for the perimeter and expand the right hand side:

Simplify the right hand side:

Add 36 to both sides:

Divide both sides by 12:

Now that we know the value for s, let's deduce the lengths of the sides:

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
