Question

the base of a triangular field is three times its altitude .If the cost os sowing the field at rupees 58 per hectare is rupees 783 find its base and height​

Answer 1

Answer:

Given that b=3h

Area=21×bh

Area=21×(3h)h

Area=21×3h2

Given that 

⇒58×21×3h2=783

⇒3h2=27

⇒h2=9

⇒h=300m

⇒b=900m

Answer 2

Answer:

∴ area=(12×base×altitude)=(12×3x×x)m2=3x22m2. But, area=total cost of sowingrate per hectare=78358hectares=(272×10000)m2=135000m2. ∴ 3x22=135000⇒x2=90000⇒x=300.
