Given:
Perimeter of a square = 
To find:
The side length of the square.
Solution:
We know that, the perimeter of the square is 4 times of its side length.
Where, a is the side length.
Perimeter of a square =
Now,

let x be the number of discount tickets sold
then the number of regular tickets sold is 6x
the total tickets sold is 1456, thus
x + 6x = 1456
7x = 1456 ( divide both sides by 7 )
x = 208
number of discount tickets sold = 208
≠ 208
but 
= 208
Earl is incorrect , dividing by 7 gives the amount sold
Number 3 is 8 inches. number 4 is 16. number 5 is 135 ft.

Problem-solving is the act of defining trouble; figuring out the cause of the problem; figuring out, prioritizing, and choosing alternatives for an answer; and enforcing a solution.
Problem-fixing starts with identifying the difficulty. For instance, a teacher might want to discern the way to improve student performance on a writing talent test. To do that, the trainer will assess the writing checks looking for areas of development.
