Write a real world problem that involves classifying a quadrilateral then solve the problem.

An amusement park ride has a moving platform attached to four swinging arms. The platform swings back and forth, higher and higher, until it goes over the top and around in a circular motion. In the diagram below, AD and BC represent two of the swinging arms, and DC is parallel to the ground
(line l). Explain why the moving platform AB is always parallel to the ground.

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
