xatiple 4 : 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 (see Fig. 12.11). She divided
the field in two parts by joining the mid-point of the longest side to the opposite vertex
and grew patatoes in one part and onions in the other part. How much area (in hectares)
Potatoes and onions? (1 hectare = 10000 m²)
Suppose that a farmer has a land to be cultivated and she employs some labourers for
this purpose on the terms of wages calculated by area cultivated per square metre.
How will she do this? Many a time, the fields are in the shape of quadrilaterals. We
