According to the condition of this task, it is required to calculate the perimeter of a rectangle if the length of its two adjacent sides is specified. The length of the perimeter of a rectangle is equal to the sum of all its sides. Since in a rectangle the opposite sides are equal to each other, then the perimeter will be defined as twice the length of its two adjacent sides.
