Question

the base of triangular field is three time its altitude if the cost of sowing the field at rs. 58 per hactare is rs. 783 find its base and height
​

Answer 1

Answer:

Step-by-step explanation:

let the altitude of the triangle be y

base=3y

area of a triangle = 1\2 x base x altitude

=1\2 x 3y  x y

=1\2 x 3y^2\2

cost of sowing the field at rs 58 per hectare = 58 x 3x2/2 = 87 x 2

∴87 x 2 = 783

y^2=783/87  = 9

y=3

base=3(3)=9

the base = 9 and the altitude.
