Calculate the Area of a Square with Side Length 3: Visual Geometry Problem

Question

Look at the square below:

What is the area of the square?

00:00 Find the area of the square

00:03 The length of the square's side according to the given data

00:07 Use the formula to calculate the square's area (side squared)

00:14 Substitute appropriate values and solve to find the area

00:20 And this is the solution to the problem

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 diagram provides us with one side of the square, and in a square all sides are equal, we will solve the area of the square as follows:

$A=3^2=9$

$9$
