Solution Steps

00:00 Calculate the perimeter of rectangle ABCD
00:03 Opposite sides are equal in a rectangle
00:10 The perimeter of the rectangle equals the sum of its sides
00:19 Let's substitute appropriate values and solve for the perimeter
00:26 And this is the solution to the problem

Step-by-Step Solution

In the drawing, we have a rectangle, although it is not placed in its standard form and is slightly rotated,
but this does not affect that it is a rectangle, and it still has all the properties of a rectangle.
 
The perimeter of a rectangle is the sum of all its sides, that is, to find the perimeter of the rectangle we will have to add the lengths of all the sides.
We also know that in a rectangle the opposite sides are equal.
Therefore, we can use the existing sides to complete the missing lengths.
 
4.8+4.8+12+12 =
33.6 cm

Answer

33.6 cm
