Calculate the Area of a Square: Finding Square Units for 40-Unit Side Length

Question

Look at the square below:

What is the area of the square?

00:00 Find the area of the square

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

00:07 We'll use the formula for calculating the area of a square (side squared)

00:11 We'll substitute appropriate values and solve to find the area

00:18 And this is the solution to the problem

Remember that the area of the square is equal to the side of the square raised to the second power

The formula for the area of the square is:

$A=L^2$

We calculate the area of the square:

$A=40^2=1600$

$1600$
