D. 9 cm because a times b equals c
$1.00 per 8 ounces
This is not the unit rate , because this $1.00 is the rate for 8 units , not for 1 unit , while all other options have rate for 1 unit only.
The correct answer is 22.6
This shape is the rhombus, then ;
<h3>Rhombus area = side length × height </h3><h3 />
A= b × h
A= Rhombus area
h = height ; b = side length ( length of any side)
h= 3 inch ; b= 4.5 inch ; A=?
A= b × h
A= 4.5 × 3 = 13.5 inch²

<h3>
The perimeter of a rhombus = 4 × side of length</h3>
P = 4× a
P = The perimeter of a rhombus ; a = side of length
p= ? ; a = 4.5 inch
P = 4× a
P = 4× 4.5 = 18 inch
