The side of a square measures 2x²y. What is the area of the square if x
= -2 and y = 2? Do not use commas in your answer.

Answer 1

Answer:

The area of the square when x  = -2 and y = 2 is 256 sq. units.

Step-by-step explanation:

The side of the square = $2x^2 y$

Now, AREA OF THE SQUARE = SIDE x SIDE

⇒ Area of the square  is:

$(2x^2 y) \times (2x^2 y)\\=   (2x^2 y)^2   = 4x^4y^2$

So, the area of the square is  $4x^4y^2$

Now, to find the area when x = -2 and y = 2

So, $4x^4y^2  \implies 4 (-2)^4 (2)^2\\=4 \times16 \times 4 = 256$

⇒The area of the square when x  = -2 and y = 2 is 256 sq. units.
