Common Mistakes to Avoid When Calculating the Square of 581
Mistakes are common among kids when doing math, especially when it is 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 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 misuse it as (5+8+1)² or (500+80+1)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 error.
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 581
Problem 1
Find the length of the square, where the area of the square is 337,561 cm².
The area of a square = a² So, the area of a square = 337,561 cm² So, the length = √337,561 = 581. The length of each side = 581 cm
Explanation
The length of a square is 581 cm.
Because the area is 337,561 cm², the length is √337,561 = 581.
Problem 2
Sarah is planning to tile her square patio of length 581 feet. The cost to tile a square foot is 5 dollars. Then how much will it cost to tile the full patio?
The length of the patio = 581 feet The cost to tile 1 square foot of patio = 5 dollars. To find the total cost to tile, we find the area of the patio, Area of the patio = area of the square = a² Here a = 581 Therefore, the area of the patio = 581² = 581 × 581 = 337,561. The cost to tile the patio = 337,561 × 5 = 1,687,805. The total cost = 1,687,805 dollars
Explanation
To find the cost to tile the patio, we multiply the area of the patio by the cost to tile per foot.
So, the total cost is 1,687,805 dollars.
Problem 3
Find the area of a circle whose radius is 581 meters.
The area of the circle = 1,061,143.22 m²
Explanation
The area of a circle = πr²
Here, r = 581
Therefore, the area of the circle = π × 581² = 3.14 × 581 × 581 = 1,061,143.22 m².
Problem 4
The area of the square is 337,561 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 337,561 cm²
The length of the side is √337,561 = 581
Perimeter of the square = 4a
Here, a = 581
Therefore, the perimeter = 4 × 581 = 2,324.
Problem 5
Find the square of 582.
The square of 582 is 338,724
Explanation
The square of 582 is multiplying 582 by 582.
So, the square = 582 × 582 = 338,724
