Kamla has a triangular field with sides $240 \, m, 200 \, m, 360 \, m$,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. She divided the field in two parts by joining the mid-point of the longest side to the opposite vertex and grew potatoes in one part and onions in the other part. How much area (in hectares) has been used for wheat,potatoes and onions? $(1 \, \text{hectare} = 10000 \, m^2)$

• A
  $2.26 \, \text{hectares for wheat, } 1.92 \, \text{hectares for potatoes, } 1.92 \, \text{hectares for onions}$
• B
  $1.92 \, \text{hectares for wheat, } 2.26 \, \text{hectares for potatoes, } 2.26 \, \text{hectares for onions}$
• C
  $31.92 \, \text{hectares for wheat, } 1.92 \, \text{hectares for potatoes, } 1.92 \, \text{hectares for onions}$
• D
  $51.92 \, \text{hectares for wheat, } 2.26 \, \text{hectares for potatoes, } 2.26 \, \text{hectares for onions}$
