How to Calculate the Values of Squares 1 to 30?

In order to calculate the squares of 1 to 30, we can use any one of the following methods:

Method 1: Multiplication by itself

In this method, the number is multiplied by itself and the resultant product gives us the square of that number. For example, the square of 4 = 4 × 4 = 16. Here, the resultant product '16' gives us the square of the number '4'. This method works well for smaller numbers.

Method 2: Using basic algebraic identities

In this method, a given number ‘n’ is first expressed in the form of either (a+b) or (a-b), where ‘a’ is a multiple of 10 and ‘b' is any number less than 10. Next, the basic algebraic identities formula is used to find the square of the given number. We can use any of the 2 basic algebraic identities formulas to calculate the square of a given number. (a + b)² = a² + b² + 2ab or (a - b)² = a² + b² - 2ab. The form where ‘b’ has a smaller value should be preferred.

For example, to find the square of 29, we can express 29 as

Option 1: (20 + 9)
Option 2: (30 - 1)

In the next step, we use the basic algebraic identity formula and get Option 1: [20² + 9² + (2 × 20 × 9)] or Option 2: [30² + 1² - (2 × 30 × 1)]. Solving the expressions further, we get Option 1: (400 + 81 + 360) = 841 or Option 2: (900 + 1 - 60) = 841.

Solved Examples on Squares of 1 to 30

Example 1: If a circular tabletop has a radius of 16 inches, what is the area of the tabletop in sq. inches?

Solution:

Area of circular tabletop = πr² = π (16)²

Let us use the values from the squares of 1 to 30 chart and we get 16² = 256

Area = 256π

Therefore, the area of the tabletop = 804.57 inches².
Example 2: Find the area of a square window whose side length is 25 inches.

Solution:

Area of the square window (A) = Side²

Using the square table 1 to 30, we get, Area = 25² = 625

Therefore, the area of the window is 625 inches²
Example 3: Two square wooden planks have sides 10 m and 12 m respectively. Find the combined area of both the wooden planks?

Solution:

Area of wooden plank = (side)²

Let us use the chart of squares upto 30 to solve this question.

⇒ Area of 1st wooden plank = 10² = 100 m²

⇒ Area of 2nd wooden plank = 12² = 144 m²

Therefore, the combined area of wooden planks is 100 + 144 = 244 m²
Example 4: What is the square of 15?

Solution:

Using values from square table 1 to 30 chart, we can get the square of 15 which is 15² = 225
