Answer:

28k

Explanation:

The perimeter is the sum of the four equal-length sides:

P = 7k +7k +7k +7k

P = k(7 +7 +7 +7)

P = 28k . . . . perimeter of the rhombus

__

Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.
