Answer 1

Answer:

C. 4s < 20

Step-by-step explanation:

One side measures s. The perimeter is the sum of the lengths of the 4 sides, so the perimeter is s + s + s + s. Since all side lengths are equal, the perimeter is simply 4s. The perimeter is less than 20 inches, so 4s must be less than 20.

The inequality is

C. 4s < 20
