Question

The base of a triangular field is three times it's altitude. If the cost of sowing the field at Rs.58 hectare is 783, find it's base and hight.

Answer 1

let x be the altitude so it's base is 3x
= area of triangle = 783÷58
or, 1/2 x base x height = 13.5
or, 3x X x = 27
or, x^2= 9
or, x = √9
or x = 3
base is 3x = 3 x 3 = 9
height =3
