Common Mistakes to Avoid When Calculating the Square of 2645
Mistakes are common among kids when doing math, especially when it comes to 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 the steps or else by swapping the digits. To avoid it, students should double-check the answer. 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 2645² with (2+6+4+5)² or (2600+45)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
Mistake 3
Confusing with square and square root.
Not understanding the concept of square and square root can lead to confusion in students. To avoid it, 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. So, students should understand parentheses. And do the operations in the correct order to avoid errors.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square of a number. So students should do regular practice to avoid errors.
Solved Examples on Square of 2645
Problem 1
Find the length of the square, where the area of the square is 6,998,025 cm².
The area of a square = a²
So, the area of a square = 6,998,025 cm²
So, the length = √6,998,025 = 2645.
The length of each side = 2645 cm
Explanation
The length of a square is 2645 cm.
Because the area is 6,998,025 cm², the length is √6,998,025 = 2645.
Problem 2
Sarah wants to tile her square garden with each side measuring 2645 feet. The cost to tile a square foot is 2 dollars. How much will it cost to tile the entire garden?
The length of the garden = 2645 feet
The cost to tile 1 square foot = 2 dollars.
To find the total cost to tile, we find the area of the garden,
Area of the garden = area of the square = a²
Here a = 2645
Therefore, the area of the garden = 2645² = 2645 × 2645 = 6,998,025.
The cost to tile the garden = 6,998,025 × 2 = 13,996,050.
The total cost = 13,996,050 dollars
Explanation
To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot.
So, the total cost is 13,996,050 dollars.
Problem 3
Find the area of a circle whose radius is 2645 meters.
The area of the circle = 21,978,562.25 m²
Explanation
The area of a circle = πr²
Here, r = 2645
Therefore, the area of the circle = π × 2645² = 3.14 × 2645 × 2645 = 21,978,562.25 m².
Problem 4
The area of the square is 6,998,025 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 6,998,025 cm²
The length of the side is √6,998,025 = 2645
Perimeter of the square = 4a
Here, a = 2645
Therefore, the perimeter = 4 × 2645 = 10,580.
Problem 5
Find the square of 2646.
The square of 2646 is 7,003,316
Explanation
The square of 2646 is multiplying 2646 by 2646.
So, the square = 2646 × 2646 = 7,003,316
