Answer:

B

Explanation:

area of a square = s² ( s is the side length )

here s = x + y, hence

area = (x + y)² ← expand using FOIL )

= x² + xy + xy + y² = x² + 2xy + y² → B

Answer:

B. area = x^2 + 2xy + y^2

Explanation:

Area of square with side s is s^2.

This square has side x + y, so

area = (x + y)^2

area = (x + y)(x + y)

area = x^2 + xy + xy + y^2

area = x^2 + 2xy + y^2
