Common Mistakes to Avoid When Calculating the Square of 99999
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 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 while using the formula.
The formula to find the square of the number is a². Instead, students may use 99999² with (9999 + 9)² or (90000 + 9999)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 99999
Problem 1
Find the length of the square, where the area of the square is 9999800001 cm².
The area of a square = a² So, the area of a square = 9999800001 cm² So, the length = √9999800001 = 99999. The length of each side = 99999 cm
Explanation
The length of a square is 99999 cm.
Because the area is 9999800001 cm², the length is √9999800001 = 99999.
Problem 2
Lisa is planning to build a square garden of length 99999 feet. The cost to build a foot is 0.5 dollars. Then how much will it cost to build the full garden?
The length of the garden = 99999 feet The cost to build 1 square foot of the garden = 0.5 dollars. To find the total cost to build, we find the area of the garden, Area of the garden = area of the square = a² Here a = 99999 Therefore, the area of the garden = 99999² = 99999 × 99999 = 9999800001. The cost to build the garden = 9999800001 × 0.5 = 4999900000.5. The total cost = 4999900000.5 dollars.
Explanation
To find the cost to build the garden, we multiply the area of the garden by the cost to build per foot.
So, the total cost is 4999900000.5 dollars.
Problem 3
Find the area of a circle whose radius is 99999 meters.
The area of the circle = 31415488255.86 m²
Explanation
The area of a circle = πr²
Here, r = 99999
Therefore, the area of the circle = π × 99999² = 3.14 × 99999 × 99999 = 31415488255.86 m².
Problem 4
The area of a square is 10000000000 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 10000000000 cm²
The length of the side is √10000000000 = 100000
Perimeter of the square = 4a
Here, a = 100000
Therefore, the perimeter = 4 × 100000 = 400000.
Problem 5
Find the square of 100000.
The square of 100000 is 10000000000
Explanation
The square of 100000 is multiplying 100000 by 100000.
So, the square = 100000 × 100000 = 10000000000
