here is the choices, 16 cm, 12 cm, 10 cm, 14 cm
Is the problem missing another given information? I try to solved it using two different formula in solving area of trapezoid but no good.
You can put this solution on YOUR website! Ok, i finally get the answer to my question. the answer is 16 cm. Im running out of time in writing my solution, so may be next time i will show it. By the way i break the trapezoid into to 2 right triangles and 1 rectangle and add its areas, then i came up with this equation then to get the maximum area, derive with respect to x and get the roots of x, the answer is 4 and -8 so the 4th sides is
