What Are the Basic Formulas for Finding the Surface Area of Squares and Rectangles?

Hey there, young mathematicians! Are you ready to explore the exciting world of surface areas? Let’s find out the simple formulas for calculating the surface area of two cool 2D shapes: squares and rectangles!

1. Surface Area of a Square:

A square is a special shape with all sides the same length.

To find the surface area (A) of a square, you can use this formula:

A = s²

Here, s is the length of one side of the square.

So, if you know how long one side is, just multiply it by itself! That’s what squaring means. How awesome is that?

2. Surface Area of a Rectangle:

Now, let’s look at rectangles.

Rectangles have two sides that are the same length and two sides that are the same width.

To find the surface area (A) of a rectangle, you can use this formula:

A = l × w

In this formula, l stands for the length, and w stands for the width of the rectangle.

By multiplying these two numbers, you can find the area for any rectangle. It doesn’t matter how long or wide it is!

Summary:

• Square: A = s²
• Rectangle: A = l × w

So, when you’re solving problems about squares and rectangles, just remember these formulas! They will help you find the answers and understand the amazing world of geometry.

Don’t forget to practice with different shapes! Math isn’t just about numbers; it’s about discovering new things and having fun. Enjoy your calculations!
