I dont want a direct answer. I would like to know how to solve it

OpenStudy (anonymous):

A= (1/2) · (b1+b2) · h

OpenStudy (anonymous):

So i just plug in the numbers into the equation?

OpenStudy (anonymous):

can you show me how to correctly plug the numbers into the equation

OpenStudy (anonymous):

The 44in is there to throw you off; base 1 and base 2 are the same. (1/2) x (38+38) x 35

OpenStudy (anonymous):

That equals 1330. That can't be right

OpenStudy (anonymous):

The angles are congruent on adjacent sides, I'm pretty sure it's correct. Are you given any choices?

OpenStudy (anonymous):

no. Its a question where I have to answer it step by step

OpenStudy (anonymous):

1330 square inches is the answer I came up with. The reason why I threw out the 44 inches was because of the angles that are in a trapezoid and they are congruent, so usage of the Pythagorean's Theorem is not required to solve for the length of the angle of the triangle to the dotted line of the height (as it is already included in the top base 38in.)

Oh, i understand. Thanks for the explanation. :)
