Formula of area of square
------------------------------------------------------------------
Area of square = Length x Length
Area of square = Length2

------------------------------------------------------------------
Given information

Answer:

Product means to multiply.

No more than 30 is basically it can be 30 OR less nothing more.
k(-5) ≤ 30
Thats your inequality.

Solution is easy.
-5k ≤ 30
Divide -5
k ≥ 6
k ≥ 6 since when you divide or multiply by a negative number the inequality is flipped.

k≥ 6 is your solution .
