Question

the base of a triangular field is three times its altitude. If the cost of sowing the field at RS 58per hectare is RS783,find its base and height.​

Answer 1

ITS CORRECT

AND I CAN'T COMMENT

Let the altitude of the triangle be y

Then the base will be 3y

Area of triangle is 1/2 x base x altitude

=1/2 x 3y x y

= 1/2 x 3y^{2}

= 3y^{2} /2

Cost of sowing the field at rs 58 per hectare = 58 × 3x2/2 = 87x2

Therefore, 87x2 = 783

y^{2} = 783/87 = 9

⇒ y = 3

Base = 3(3) = 9

Hence base is 9 and altitude is 3.
