How to Calculate Squares from 1 to 40
There are simple ways to find square numbers quickly:
1. Multiply the number by itself. For example, square of 18 is 18 × 18 = 324.2. Use algebraic identities. For example, to find 23², write 23 as 20 + 3 and use (a + b)² = a² + 2ab + b²:
3. Learn patterns for ending digits. For example, numbers ending in 5 always have squares ending in 25.
4. Practice with square number tables like the one above for fast recall in exams.
Worked Example – Solving a Problem
1. What is the area of a square playground if one side is 24 metres?Step 2: Substitute side = 24.
Step 3: Area = 24 × 24 = 576.
Step 4: Final answer: The area is 576 square metres.
2. Find the square root of 529.
Step 2: 23 × 23 = 529.
Step 3: So, √529 = 23.
