Hello!

The perimeter of a rectangle is length + length + width + width

We have to make an expression to find this where length is x and width is 4 meters shorter

since the length is x that is

lengths = 2x

The width is 4 meters shorter than x so

widths = 2(x - 4)

Combine these

The answer is 2x + 2(x - 4)

Hope this helps!
