Answer:
4x.
Step-by-step explanation:
we will begin by solving the problems.
after we have done that we will find the perimeter.
remember: The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.
so the equation is 1x + 1x + 1x + 1x
