Find the perimeter of the rectangle. A rectangle with length 12 millimeters. The area of the rectangle is marked as 132 square millimeters.

46

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

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
