Question

The base of a triangular field is three times its altitude of the cost of levelling the field at₹30.50 per sq.meter is ₹7350,find its base and height

Answer 1

let the altitude of the triangular field be h. then base of the triangle will be 3h.

Area of triangle =1/2×base×height.

=1/2×3h×h

=3/2h^2

cost of levelling =7350

=3/2×h^2×30.50=7350

=91.5h^2=14700

h^2=14700/91.5=160.65

h=12.67

so altitude of triangle=12.67m

base =12.67×3=38.01 m

:-)hope it helps u.
