Calculate the Area of a Square with Side Length 13 Units

Question

Look at the square below:

What is its area?

00:00 Find the area of the square

00:03 Find the side length of the square according to the given data

00:07 Use the formula to calculate the area of a square (side squared)

00:11 Substitute appropriate values and solve to find the area

00:18 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 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:

$A=13^2=169$

$169$
