Question

the base of a triangle field is three times it's altitude. if the cost of levelling the field at rupees 30.50 per sq.m is rupees 6588, find it's base and height​

Answer 1

Step-by-step explanation:

First of all let's find out the area of triangle

Area of triangle = 6558/30.50

=. 215 sq.m

Let the altitude of triangle y and base is 3y.

Area of triangle = 1/2 b×h

1/2 × 3y × y=. 215

3ysq. = 215 × 2

y = √430

y = 20.7m

height =. y = 20.7m

base =. 3y = 20.7m×3

= 62.1m
