Tips and Tricks for the Square of 749 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 749
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.
Solved Examples on Square of 749
Problem 1
Find the length of the square, where the area of the square is 561,001 cm².
The area of a square = a² So, the area of a square = 561,001 cm² So, the length = √561,001 = 749. The length of each side = 749 cm
Explanation
The length of a square is 749 cm. Because the area is 561,001 cm², the length is √561,001 = 749.
Problem 2
Tom is planning to paint his square wall of length 749 feet. The cost to paint a foot is 3 dollars. Then how much will it cost to paint the full wall?
The length of the wall = 749 feet The cost to paint 1 square foot of wall = 3 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 749 Therefore, the area of the wall = 749² = 749 × 749 = 561,001. The cost to paint the wall = 561,001 × 3 = 1,683,003. The total cost = 1,683,003 dollars
Explanation
To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 1,683,003 dollars.
Problem 3
Find the area of a circle whose radius is 749 meters.
The area of the circle = 1,761,932.03 m²
Explanation
The area of a circle = πr² Here, r = 749 Therefore, the area of the circle = π × 749² = 3.14 × 749 × 749 = 1,761,932.03 m².
Problem 4
The area of the square is 561,001 cm². Find the perimeter of the square.
The perimeter of the square is 2,996 cm.
Explanation
The area of the square = a² Here, the area is 561,001 cm² The length of the side is √561,001 = 749 Perimeter of the square = 4a Here, a = 749 Therefore, the perimeter = 4 × 749 = 2,996 cm.
Problem 5
Find the square of 750.
The square of 750 is 562,500.
Explanation
The square of 750 is multiplying 750 by 750. So, the square = 750 × 750 = 562,500.
