The sides of a triangle are 35 cm., 54 cm. and 61 cm. respectively the length of it's altitude is

Posted by Hrutvi Thaker (Mar 22, 2017 1 p.m.) (Question ID: 4389)

  • Answers:
  • Using Heron's formula

    s = (35 + 54 + 61)/2 = 75 cm

    Area of trianlge = {s(s - a)(s - b)(s - c)}1/2 

    = {75(75 - 35)(75 - 54)(75 - 61)}1/2 

    = {75 × 40 × 21 × 14}1/2 

    = 210√10 sq.cm

    Now Area of triangle = 1/2 × base x altitude

    210√10 = 1/2 × 35 × altitude

    Altitude = 12√10 cm

How did restiction on pasture lands affect the animals stock explain.

Posted by Tanisha Jain (Mar 22, 2017 9:29 a.m.) (Question ID: 4384)

  • Answers:
  • Ans. The Forest Act changed the lives of pastoralists in a great extent. The pastoralists now prevented from entering many forests that provided valuable forage for their cattle earlier times.

    The pastoralists needed a permit for entry in the forests. In most pastoral tracts of India, Grazing Tax was imposed. The number of cattle and the amount of tax were entered on the pass.

    The grazing lands came to be continuously used and the quality of pastures declined as a result of imposing restrictions on the pastoral movements.

    Thus, the over restriction of their movement created a shortage of forage for animals and the deterioration of animal stock. Underfed cattle died in large numbers during scarcities and famines.
