Answer:
5 meters
Step-by-step explanation:
The length of the sides of the rectangle on the right are as follows: 8, 8, 4, 4.
The perimeter of the rectangle on the left is 5/4 of the one on the right.
So, the lengths of the sides are also 5/4 of the sides of the right rectangle.
The lengths of the sides of the rectangle on the left are: 10, 10, 5, 5.
Which means that x = 5 meters!
