Area of Square: Calculate Using Expression 4X+4Y

Question

Look at the following square:

Which expression represents its area?

00:00 Express the area of the square

00:03 Side length according to the given data

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

00:17 We'll substitute appropriate values and solve to find the area

00:32 And this is the solution to the question

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:

$S=(4x+4y)^2$

$(4y+4x)^2$
