How to Calculate the Values of Squares 1 to 40?
To calculate the squares of 1 to 40, 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 3 = 3 × 3 = 9. Here, the resultant product “9” gives us the square of the number “3”. This method works well for smaller numbers.
Method 2: Using basic algebraic identities: To find the square of 23, we can express 23 as:
 Option 1: (20 + 3)
 Option 2: (30  7)
In the next step, we use the basic algebraic identity formula and get Option 1: [20^{2} + 3^{2} + (2 × 20 × 3)] or Option 2: [30^{2} + 7^{2}  (2 × 30 × 7)]. Solving the expressions further, we get Option 1: (400 + 9 + 120) = 529 or Option 2: (900 + 49  420) = 529.
Solved Examples on Square 1 to 40

Example 1: If a circular tabletop has a radius of 40 inches. Find the area of the tabletop in sq. inches? [π = 3.14]
Solution:
Area of circular tabletop = πr^{2} = π (40)^{2}
Using values from square table 1 to 40;
i.e. A = 1600π
Answer: ∴ The area of the tabletop = 5024 inches^{2}.

Example 2: Find the area of a square window whose side length is 32 inches.
Solution:
Area of square window (A) = Side^{2}
i.e. A = 32^{2} = 1024
Answer: The area of a square window is 1024 inches^{2}.

Example 3: Two square wooden planks have sides 20m and 25m respectively. Find the combined area of both wooden planks?
Solution:
Area of wooden plank = (side)^{2}
⇒ Area of 1^{st} wooden plank = 20^{2} = 400 m^{2}
⇒ Area of 2^{nd} wooden plank = 25^{2 }= 625 m^{2}
Answer: ∴ Combined area of wooden planks is 400 + 625 = 1025 m^{2}

Example 4: Find the sum of the first 40 odd numbers.
Solution:
The sum of first n odd numbers is given as n^{2}
⇒ Sum of first 40 odd numbers (n) = 40^{2}
Using values from squares of 1 to 40 chart, the sum of first 40 numbers = 40² = 1600
Answer: The sum of the first 40 odd numbers is 1600.
