Answer:
46 [tex]millimeters^{2}[/tex]
Step-by-step explanation:
What is given....
The length which is 12.
The area which is 132
We can use both of those to find the missing height
A = l * h
132 = 12 * h
132/12 = 12/12 * h
11 = h
Now that we found what "h" is, we can use that to find the perimeter....
Perimeter is when you add up all of the sides of a shape
L = 12
H = 11
There are 4 sides in a rectangle ( 2 sides for the height, and 2 sides for the lengths)
12 + 12 + 11 + 11
24 + 22
46
The perimeter of the rectangle is 46 [tex]millimeters^{2}[/tex]
Hope this helped!
