Step 3: Press the equal to button to find the answer Here, the square of 65 is 4225.
Tips and Tricks for the Square of 4225
Tips and tricks make it easy for students to understand and learn the square of a number. To master the square of a number, these tips and tricks will help students:
- The square of an even number is always an even number. For example, 6² = 36.
- The square of an odd number is always an odd number. For example, 5² = 25.
- The last digit of the square of a number is always 0, 1, 4, 5, 6, or 9.
- If the square root of a number is a fraction or a decimal, then the number is not a perfect square. For example, √1.44 = 1.2.
- The square root of a perfect square is always a whole number. For example, √144 = 12.
Common Mistakes to Avoid When Calculating the Square of 4225
Mistakes are common among kids when doing math, especially when it involves finding the square of a number. Let’s learn some common mistakes to master the squaring of a number.
Mistake 1
Calculation errors:
Calculation errors mostly happen when students skip steps or swap the digits. To avoid this, students should double-check their answers. They can double-check by finding the square root of the solution they found.
For example, the square of 25 is 625, and the square root of 625 is ±25.
Mistake 2
Errors when using the formula.
The formula to find the square of the number is a². Instead, students may use 652 as (6 + 5)² or (60 + 5)². Students should check and use the correct formula and double-check their answers to avoid confusion.
Mistake 3
Confusing square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid this, students should understand the concept that square and square root are inverse operations. The square of 5 is 25 and the square root of 25 is ±5.
Mistake 4
Errors in parentheses.
Ignoring the parentheses when finding the square of a number can lead to errors. Students should understand parentheses and perform operations in the correct order to avoid error.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. Students should do regular practice to avoid errors.
Solved Examples on Square of 4225
Problem 1
Find the side length of a square whose area is 4225 cm².
The area of a square = a²
So, the area of a square = 4225 cm²
So, the side length = √4225 = 65.
The length of each side = 65 cm
Explanation
The length of a square is 65 cm because the area is 4225 cm², so the length is √4225 = 65.
Problem 2
Sarah wants to tile her square floor of side 65 feet. The cost to tile one square foot is 4 dollars. How much will it cost to tile the entire floor?
The side length of the floor = 65 feet
The cost to tile 1 square foot of floor = 4 dollars.
To find the total cost to tile, we find the area of the floor.
Area of the floor = area of the square = a²
Here a = 65
Therefore, the area of the floor = 65² = 65 × 65 = 4225.
The cost to tile the floor = 4225 × 4 = 16900.
The total cost = 16900 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot.
So, the total cost is 16900 dollars.
Problem 3
Find the area of a circle whose radius is 65 meters.
The area of the circle = 13,273.39 m²
Explanation
The area of a circle = πr²
Here, r = 65
Therefore, the area of the circle = π × 65² = 3.14 × 65 × 65 = 13,273.39 m².
Problem 4
The area of a square is 4225 cm². Find the perimeter of the square.
The perimeter of the square is 260 cm.
Explanation
The area of the square = a²
Here, the area is 4225 cm²
The side length is √4225 = 65
Perimeter of the square = 4a
Here, a = 65
Therefore, the perimeter = 4 × 65 = 260.
Problem 5
Find the square of 66.
The square of 66 is 4356.
Explanation
The square of 66 is found by multiplying 66 by 66.
So, the square = 66 × 66 = 4356.
