ANSWER:
2x^2 + 6x
The area of the rose garden is equivalent to:
2x^2 + 6x.
STEP-BY-STEP EXPLANATION:
The rose garden is a rectangle.
Area of a rectangle = length × width
Let the area of the rose garden = A
Length of rose garden = x + 3
Width of rose garden = 2x
THEREFORE:
A = ( 2x ) ( x + 3 )
A = 2x^2 + 6x
