Đáy lớn: 55m
Đáy nhỏ: \(\frac{3}{5} \times 55 = 33 m\)

Chiều cao:
\(\frac{55 + 33}{2} = 44 m\)

a) Diện tích thửa ruộng:

\(S = \frac{\left(\right. 55 + 33 \left.\right) \times 44}{2}\)
\(S = \frac{88 \times 44}{2}\)
\(S = 44 \times 44\)
\(S = 1936 \textrm{ } m^{2}\)

b) Số thóc thu hoạch:

\(1936 : 100 = 19 , 36\)

\(19 , 36 \times 65 = 1258 , 4 \textrm{ } k g\)

Đổi ra tạ:

\(1258 , 4 : 100 = 12 , 584 \textrm{ } t ạ\)

Đáp số:
a) \(1936 \textrm{ } m^{2}\)
b) \(12 , 584 \textrm{ } t ạ\)
