The area of a square is 72.25 cm2 . Find its perimeter (in cm).a)68b)...
Given information:
- The area of a square is 72.25 cm².
To find:
- The perimeter of the square.
Formula:
- The area of a square = side²
- The perimeter of a square = 4 × side
Solution:
1. Let's assume the side of the square as "s".
2. According to the given information, the area of the square is 72.25 cm², so we can write it as:
s² = 72.25
Taking the square root on both sides, we get:
s = √72.25
s = 8.5 cm
3. Now, using the formula for the perimeter of a square, we can calculate it as:
Perimeter = 4 × side
Perimeter = 4 × 8.5 cm
Perimeter = 34 cm
Therefore, the perimeter of the square is 34 cm. Hence, option C is the correct answer.
