Calculate the Area of a Square with Side Length 10 Units

Q: Why do I square the side length instead of just doubling it?

Area measures the space inside a shape. For a square with side 10, you need 10 rows of 10 unit squares = 10 × 10 = 100 square units total!

Q: What's the difference between area and perimeter?

Perimeter is the distance around the square (4 × 10 = 40). Area is the space inside the square (10² = 100). Think: fence around vs. grass inside!

Q: Do I always use the same formula for any square?

Yes! The formula $ A = s^2 $ works for any square, no matter how big or small. Just substitute your side length for s.

Q: What if the side length is a decimal or fraction?

The same rule applies! For side length 2.5: $ A = 2.5^2 = 6.25 $. For side $ \frac{1}{2} $: $ A = (\frac{1}{2})^2 = \frac{1}{4} $

Q: How can I remember that area uses squaring?

Think "square the square"! Also remember that area is always measured in square units (like square inches or square meters), which hints at the squaring operation.

Step-by-step written solution

Follow each step carefully to understand the complete solution

Understand the problem

Look at the square below:

What is the area of the square?

Step-by-step solution

The area of the square is equal to the side of the square raised to the second power.

That is:

$A=L^2$

Since the drawing gives us one side of the square, and in a square all sides are equal, we will solve the area of the square as follows:

$A=10^2=100$

Final Answer

$100$

Key Points to Remember

Essential concepts to master this topic

Rule: Area of a square equals side length squared
Technique: Use A = s² formula: 10² = 10 × 10 = 100
Check: Square with side 10 has perimeter 40 and area 100 ✓

Common Mistakes

Avoid these frequent errors

Adding side length instead of squaring
Don't calculate 10 + 10 = 20 for area! This gives you twice the side length, not the area. Area measures space inside the square, which requires multiplying length × width. Always use A = s² and square the side length.
