    Well, not explicitly. What is the formula for the perimeter?

    perimeter = all the sides the 2 sides are the same p=14+8+2x

    Can you figure out the height of the trapezoid?

    "44?" isn't an answer choice. When we're done, you'll definitely know what the answer is.

    the height is 4? ... and yes, 44 is an answer choice.

    44 is an answer choice. "44?" is not.

    There's a difference between taking a stab at an answer, and understanding what you've done so that you know what the answer is.

    My old math teacher would always say "is that an answer, or a prayer?" :-)

    I know the height is 4, and the area is 44. I want to make sure that you can look at a problem like this and find the answer and be confident that you've done it right. That's a good outcome, right?
