Step 3: Press the equal button to find the answer Here, the square of 771 is 594,441.
Tips and Tricks for the Square of 771
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 771
Mistakes are common among kids when doing math, especially when 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 them, 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 771² with (7+7+1)² or (700+70+1)². So 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 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 771
Problem 1
Find the length of the square, where the area of the square is 594,441 cm².
The area of a square = a²
So, the area of a square = 594,441 cm²
So, the length = √594,441 = 771.
The length of each side = 771 cm
Explanation
The length of a square is 771 cm.
Because the area is 594,441 cm², the length is √594,441 = 771.
Problem 2
Sarah wants to carpet her square room of length 771 feet. The cost to carpet a square foot is 5 dollars. How much will it cost to carpet the entire room?
The length of the room = 771 feet
The cost to carpet 1 square foot of the room = 5 dollars.
To find the total cost to carpet, we find the area of the room,
Area of the room = area of the square = a²
Here a = 771
Therefore, the area of the room = 771² = 771 × 771 = 594,441.
The cost to carpet the room = 594,441 × 5 = 2,972,205.
The total cost = 2,972,205 dollars
Explanation
To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per foot.
So, the total cost is 2,972,205 dollars.
Problem 3
Find the area of a circle whose radius is 771 meters.
The area of the circle = 1,867,902.54 m²
Explanation
The area of a circle = πr²
Here, r = 771
Therefore, the area of the circle = π × 771² ≈ 3.14 × 771 × 771 = 1,867,902.54 m².
Problem 4
The area of the square is 594,441 cm². Find the perimeter of the square.
The perimeter of the square is 3084 cm
Explanation
The area of the square = a²
Here, the area is 594,441 cm²
The length of the side is √594,441 = 771
Perimeter of the square = 4a
Here, a = 771
Therefore, the perimeter = 4 × 771 = 3084 cm.
Problem 5
Find the square of 772.
The square of 772 is 595,984
Explanation
The square of 772 is multiplying 772 by 772.
So, the square = 772 × 772 = 595,984
