Guidance for solving exercise 5 on page 133 of Math 4 textbook

Exercise:
Calculate the perimeter and area of a square with a side length of 5/7 m

Solution method:
- Formula for calculating the perimeter of a square: P = a x 4 (where P is the symbol for perimeter; a is the side)
- Formula for calculating the area of a square: S = a x a or S = a² (where S is the symbol for area; a is the side)
=> Students apply the above formulas, substitute the numbers, and calculate to find the most accurate result.
