Question

Find the perimeter of the rectangle.

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

Answer 1

46

Explanation:

Answer 2

46
`millimeters^(2)`

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
`millimeters^(2)`
