Hello there!

The formula to find the area of a trapezoid is:
A = \frac{a+b}{2} h

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

A = \frac{3x+3x+4}{2} (x+2)

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.

The length of a rectangle is 4 centimeters more than twice its width of the perimeter of the rectangle is 86centimeters find the
lana66690 [7]

Answer:

Width= 13 cm

length=30cm

Step-by-step explanation:

Let the length of the rectangle be 'L'

And the width of the rectangle be 'W'

Perimeter= 86 cm

According to the statement:

        Length= 2*Width+4\\L=2W+4

Perimeter of a rectangle= 2(Length+Width)

86=2(2W+4+W)\\86/2=3W+4\\43=3W+4\\3W=43-4\\3W=39\\W=39/3\\W=13 cm\\\\Length(L)=2W+4\\=2(13)+4=26+4=30 cm\\Length=30 cm

                               Width= 13 cm

                                length=30cm
