Calculate Square Area: Side Length (8-3X) Problem

Question

Look at the following square:

What is its area?

00:00 Express the area of the square

00:03 Side length according to the given data

00:10 We'll use the formula for calculating square area (side squared)

00:19 We'll substitute appropriate values and solve to find the area

00:29 We'll reverse the writing order

00:34 And this is the solution to the question

The area of a square is equal to the side of the square raised to the 2nd power:

$S=a^2$

$S=(8-3x)^2$

$S=(-3x+8)^2$

$(-3x+8)^2$
