Tips and Tricks for the Square of 879
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 879
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 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 879² with (8+7+9)² or (800+70+9)². So students should check and use the correct formula and double-check the answers to avoid all 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 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 879
Problem 1
Find the length of the square where the area of the square is 772,641 cm².
The area of a square = a²
So, the area of a square = 772,641 cm²
So, the length = √772,641 = 879.
The length of each side = 879 cm
Explanation
The length of a square is 879 cm.
Because the area is 772,641 cm², the length is √772,641 = 879.
Problem 2
Anna is planning to wallpaper her square wall of length 879 feet. The cost to wallpaper a foot is 2 dollars. Then how much will it cost to wallpaper the full wall?
The length of the wall = 879 feet
The cost to wallpaper 1 square foot of wall = 2 dollars.
To find the total cost to wallpaper, we find the area of the wall,
Area of the wall = area of the square = a²
Here a = 879
Therefore, the area of the wall = 879² = 879 × 879 = 772,641.
The cost to wallpaper the wall = 772,641 × 2 = 1,545,282.
The total cost = 1,545,282 dollars
Explanation
To find the cost to wallpaper the wall, we multiply the area of the wall by the cost to wallpaper per foot. So, the total cost is 1,545,282 dollars.
Problem 3
Find the area of a circle whose radius is 879 meters.
The area of the circle = 2,426,140.34 m²
Explanation
The area of a circle = πr²
Here, r = 879
Therefore, the area of the circle = π × 879² = 3.14 × 879 × 879 = 2,426,140.34 m².
Problem 4
The area of the square is 772,641 cm². Find the perimeter of the square.
The perimeter of the square is 3,516 cm
Explanation
The area of the square = a²
Here, the area is 772,641 cm²
The length of the side is √772,641 = 879
Perimeter of the square = 4a
Here, a = 879
Therefore, the perimeter = 4 × 879 = 3,516.
Problem 5
Find the square of 880.
The square of 880 is 774,400
Explanation
The square of 880 is multiplying 880 by 880.
So, the square = 880 × 880 = 774,400
