Calculating Areas and Perimeters of Squares
Area of a square: A = s^2, where s is the length of one of its sides
Perimeter of a square: P = 4s, where s is the length of one of its sides
Question 1:

Question 4:
Find the area and perimeter of a square with a side length of 6 cm.
Solution:
Area = s^2 = 6 cm * 6 cm = 36 cm^2
Perimeter = 4s = 4 * 6 cm = 24 cm

Question 5:
Find the area of a square with perimeter 32 cm.
Solution:
Perimeter = 4s, where s is the side length of the square.
32 cm = 4s
s = 8 cm
Therefore, the area of the square is:
Area = s^2 = 8 cm * 8 cm = 64 cm^2

Question 6:
Find the area and perimeter of a square with a diagonal length of 10 cm.
Solution:
To find the side length of the square, we can use the Pythagorean theorem:
a^2 + b^2 = c^2, where a and b are the length of the two sides and c is the length of the hypotenuse (the diagonal of the square).
In a square, a = b, so we have:
2a^2 = c^2
a^2 = (1/2)c^2
a = (1/2)c (since a must be positive and smaller than c)
Therefore, the side length of the square is:
s = a = (1/2)c = (1/2) * 10 cm = 5 cm
Area = s^2 = 5 cm * 5 cm = 25 cm^2
Perimeter = 4s = 4 * 5 cm = 20 cm

Question 7:
A square has a perimeter of 28cm. What is the length of each side?
Solution:
Perimeter of a square = 4s,
where s is the length of each side.
Given, perimeter = 28cm
28 = 4s
s = 7cm

Question 8:
A square has a diagonal of 6√2 cm. What is the area of the square?
Solution:
Area of a square = s^2, where s is the length of each side.
The diagonal of a square is the hypotenuse of a right-angled triangle with sides s and s.
Given, diagonal = 6√2 cm
By Pythagoras theorem, (s^2 + s^2) = (6√2)^2
2s^2 = 72
s^2 = 36
Area = s^2 = 36cm^2

Question 9:
A square has an area of 121m^2. What is the length of each side?
Solution:
Area of a square = s^2, where s is the length of each side.
Given, area = 121m^2
s^2 = 121
s = 11m

Question 10:
A square has a perimeter of 40mm. What is the area of the square?
Solution:
Perimeter of a square = 4s, where s is the length of each side.
Given, perimeter = 40mm
40 = 4s
s = 10mm
Area = s^2 = 100mm^2
