Area of Square with Side Length 5+2x: Express in Algebraic Form

Question

Look at the following square:

Express the area of the square in terms of $x$ .

00:00 Express the area of the square

00:03 The side length according to the given data

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

00:13 We'll substitute appropriate values and solve to find the area

00:19 And this is the solution to the problem

Remember that the area of a square is equal to the side of the square squared.

The formula for the area of a square is:

$S=a^2$

Finally, substitute the data into the formula:

$S=(5+2x)^2$

$(5+2x)^2$
