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 this, 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 prime factorization.
Ignoring the correct prime factors when finding the square root of a number can lead to errors. So, students should thoroughly understand and correctly apply prime factorization.
Mistake 5
Not practicing regularly.
Regular practice is required to master the square root of a number. So students should engage in regular practice to avoid errors.
Solved Examples on Square Root of 7225
Problem 1
Find the length of each side of a square, where the area of the square is 7225 cm².
The area of a square = side² So, the area of a square = 7225 cm² So, the length of each side = √7225 = 85. The length of each side = 85 cm
Explanation
The length of a square is 85 cm.
Because the area is 7225 cm², the side length is √7225 = 85.
Problem 2
Anna is planning to tile her square floor with a side length of 85 feet. The cost to tile a square foot is 5 dollars. How much will it cost to tile the entire floor?
The side length of the floor = 85 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 = side² Here side = 85 Therefore, the area of the floor = 85 × 85 = 7225. The cost to tile the floor = 7225 × 5 = 36125. The total cost = 36125 dollars
Explanation
To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per square foot.
So, the total cost is 36125 dollars.
Problem 3
Find the area of a circle whose radius is 85 meters.
The area of the circle = 22,698.84 m²
Explanation
The area of a circle = πr²
Here, r = 85
Therefore, the area of the circle = π × 85² = 3.14 × 85 × 85 = 22,698.84 m².
Problem 4
The area of a square is 7225 cm². Find the perimeter of the square.
The perimeter of the square is 340 cm.
Explanation
The area of the square = side²
Here, the area is 7225 cm²
The length of the side is √7225 = 85
Perimeter of the square = 4 × side
Here, side = 85
Therefore, the perimeter = 4 × 85 = 340 cm.
Problem 5
Find the square root of 7296.
The square root of 7296 is approximately 85.42.
Explanation
The square root of 7296 is found using a calculator or approximation methods.
So, the square root ≈ 85.42
