Calculate the Area of a Square with Side Length 7

Q: Why do I square the side length instead of multiplying by 2?

Because area measures space inside the square! When you have a 7×7 grid of unit squares, you get $ 7 \times 7 = 49 $ total units of area.

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

Area = space inside (side²), Perimeter = distance around (4 × side). For our square: Area = 49, Perimeter = 28. Don't mix them up!

Q: How do I remember that 7 squared equals 49?

Think "7 times 7" or picture a 7×7 grid! You can also remember: 6² = 367² = 498² = 64

Q: What if the side length was a decimal like 7.5?

Same formula! $ A = (7.5)^2 = 7.5 \times 7.5 = 56.25 $. The area formula works for any side length.

Q: Can I use a calculator for squaring?

Absolutely! Use the x² button or multiply the number by itself. For perfect squares like 1-12, try to memorize them for faster problem solving.

Understand the problem

Given the square:

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:

$A=7^2=49$

Final Answer

$49$

Key Points to Remember

Essential concepts to master this topic

Formula: Area of square equals side length squared
Technique: Calculate $A = 7^2 = 7 \times 7 = 49$
Check: Side 7 squared gives 49, not 28 or 14 ✓

Common Mistakes

Avoid these frequent errors

Using perimeter formula instead of area formula
Don't multiply side by 4 to get 28 = wrong formula! This calculates perimeter (distance around), not area (space inside). Always use $A = L^2$ to square the side length.
