Calculate the Area of Square ABCD: Using Geometric Formulas

Question

Look at the square below:

Which expression describes its area?

00:03 Let's find the area of the square.

00:06 First, look at the side length given to us.

00:10 We use the formula: the side of the square, times itself, or side squared.

00:16 Now, let's put in the values and calculate the area. You're doing great!

00:21 And that's how we solve this problem. Well done!

The area of a square is equal to the measurement of one of its sides squared.

The formula for the area of a square is:

$S=a^2$

Hence let's insert the given data into the formula as follows:

$S=(2+x)^2$

$(2+x)^2$
