Phần gạch chân đâu bạn?

Gọi đáy lớn ad là a, đáy nhỏ bc là b, đường cao là h
Ta có: S tam giác BCD là: (b x h) : 2= 254 (cm2) => b x h = 254 x 2=508(cm) (1)

Có: S hình thang ABCD= ((a+b)x h):2=> (a x h+b x h): 2

                                                mà a=3xb

                                                  =>(3 x b x h+b x h):2   (2)

Từ (1) và (2) ta có: (3 x 508 + 508):2= S hình thang abcd

                             => 2032 : 2 =S hình thang ABCD

                             =>S hình thang ABCD= 1016(cm2)
