Kamla has a triangular field with sides 200 m, 360 m, where she grew wheat. In another triangular field with sides 240 m, 320 m, 400 m adjacent to the previous field, she wanted to grow potatoes and onions (See Fig.
). She divided the field in two parts by joining the mid-point of the longest side to the opposite vertex and green potatoes in one part and onions in the other part. How much area (in hectares) has been used for wheat, potatoes and onions ? (1 hectare = 10000 `m^2`)
