Common Mistakes to Avoid When Calculating the Square of 1111111
Mistakes are common among students 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 swap 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 1111111² with (111 + 1111)² or (1000000 + 111111)². Students should check and use the correct formula and double-check the answers to avoid all the 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 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 perform 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 practice regularly to avoid errors.
Solved Examples on Square of 1111111
Problem 1
Find the length of the square, where the area of the square is 1,234,567,654,321 cm².
The area of a square = a² So, the area of a square = 1,234,567,654,321 cm² So, the length = √1,234,567,654,321 = 1,111,111. The length of each side = 1,111,111 cm
Explanation
The length of a square is 1,111,111 cm.
Because the area is 1,234,567,654,321 cm², the length is √1,234,567,654,321 = 1,111,111.
Problem 2
Sara is planning to tile her square floor with a side length of 1,111,111 feet. The cost to tile one square foot is 5 dollars. How much will it cost to tile the entire floor?
The length of the floor = 1,111,111 feet The cost to tile 1 square foot of floor = 5 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 = 1,111,111 Therefore, the area of the floor = 1,111,111² = 1,111,111 × 1,111,111 = 1,234,567,654,321. The cost to tile the floor = 1,234,567,654,321 × 5 = 6,172,838,271,605. The total cost = 6,172,838,271,605 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 6,172,838,271,605 dollars.
Problem 3
Find the area of a circle whose radius is 1,111,111 meters.
The area of the circle = 3,879,999,913,472.38 m²
