Expert Answer

We know that

area of triangular field = cost of sewing field/ Rate of sowing = 783/58 = 13.5 hectare

1 hectare = 10000 m

^{2}13.5 hectare = 135000 m

^{2}Area of triangular field = 13.5 hectare = 135000 m

^{2}Let altitude of triangular field be h.

The base of a triangular field is three times its altitude.

Hence, base of triangular field = 2h

Area of field = 1/2 bh

1/2 3h

^{2 }= 135000we get h = 300

Hence, altitude = h = 300 m

base = 900 m
