Hello there!
The formula to find the area of a trapezoid is:
A =

Since we have everything, we just plug them in :)
A =

A = (3x+3x+4)/2 (x) + (3x+3x+4)/2 (2)
A= <span><span><span><span>3x^2</span>+<span>2x</span></span>+<span>6x</span></span>+<span>4
A = </span></span><span>3x^2+8x+4
The correct answer is option A
I hope I helped!
Please feel free to ask me any additional questions about the answer.
