Cost of ploughing field=Rate of sowing×Area of triangular field∴Area of triangular field=Cost of ploughing fieldRate of sowingArea of triangular field=5220014
50=3600Let altitude of the field be x mBase of the field=2x mArea of the field=12×Base×Altitude⇒3600=12×2x×x⇒3600=x2⇒x=60mSo, altitude of the field=60mBase of the field=2×60=120m
