Common Mistakes to Avoid When Calculating the Square of 985
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.
Mistake 2
Errors will be using the formula.
The formula to find the square of the number is a². Instead, students may use 985² with (9 + 8 + 5)² or (900 + 80 + 5)². So students should check and use the correct formula and double-check the answers to avoid all the confusion.
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 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 error.
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 985
Problem 1
Find the length of the square, where the area of the square is 970225 cm².
The area of a square = a²
So, the area of a square = 970225 cm²
So, the length = √970225 = 985.
The length of each side = 985 cm
Explanation
The length of a square is 985 cm. Because the area is 970225 cm² the length is √970225 = 985.
Problem 2
Sarah wants to cover her square garden with grass. The garden has a side length of 985 meters. The cost to cover one square meter with grass is 2 dollars. What will be the total cost to cover the garden?
The length of the garden = 985 meters
The cost to cover 1 square meter of the garden = 2 dollars.
To find the total cost to cover the garden, we find the area of the garden,
Area of the garden = area of the square = a²
Here a = 985
Therefore, the area of the garden = 985² = 985 × 985 = 970225.
The cost to cover the garden = 970225 × 2 = 1940450.
The total cost = 1940450 dollars
Explanation
To find the cost to cover the garden, we multiply the area of the garden by the cost to cover per square meter. So, the total cost is 1940450 dollars.
Problem 3
Find the area of a circle whose radius is 985 meters.
The area of the circle = 3,048,930.25 m²
Explanation
The area of a circle = πr²
Here, r = 985
Therefore, the area of the circle = π × 985²
= 3.14 × 985 × 985
= 3,048,930.25 m².
Problem 4
The area of the square is 992025 cm². Find the perimeter of the square.
The perimeter of the square is
Explanation
The area of the square = a²
Here, the area is 992025 cm²
The length of the side is √992025 = 995
Perimeter of the square = 4a
Here, a = 995
Therefore, the perimeter = 4 × 995 = 3980.
Problem 5
Find the square of 986.
The square of 986 is 972196
Explanation
The square of 986 is multiplying 986 by 986. So, the square = 986 × 986 = 972196
