panda bear jewelry wholesale The quadrilateral ABCD is the middle point of each side trapezoid E.F.G. If the area of ​​the quadrilateral EFgh is 20, is the area of ​​the trapezoid ABCD?

jewelry pins wholesale The diagonal of the waist trapezoidal is equal. Therefore, "E, F, G, and H are equivalent to the midpoint of the waist trapezoid ABCD". The height of the waist trapezoidal and the median line on the waist; the calculation formula of the trapezoidal area is 20*2 = 40.
