The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
<h3>What is the perimeter of a square?</h3>The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.
Here, (<em>a</em>) is the side of the square.
A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,
Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

Answer:
B.
Step-by-step explanation:
Given,
The time for set up the game = minutes,
Also, the time for each level of game is minutes,
If there are l levels of games,
Then the time taken in all levels of game =
Hence, the total time ( in minutes ) = Set up time + time in all level
=
We have 60-minute of free trial of the game,
So, the total time taken can not be exceed to 60 minutes,
Which is the required inequality.
Option 'B' is correct.
