Calculate the Area of a Square with Side Length 9: Basic Geometry Problem

Question

Look at the square below:

What is the area of the square?

00:00 Find the square's area

00:03 Square side length according to the given data

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

00:12 Substitute appropriate values and solve to find the area

00:24 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:

$A=9^2=81$

$81$
