Make an equation to represent the area of a square whose sides are given by the expression x + y.

A. A = 2x + 2y + 2xy
B. A = x2 + 2xy +y2
C. A = 2(x2 + y2)
D. A = x2 + y2

I got D please correct me if wrong. Thx!

Area of Square = s²

where s = side of square

if s = x + y, then

Area = (x + y)² = x² + 2xy + y²

so B, not D
