Question

Can anyone help me with question 14

Answer 1

Answer:

height of the triangle is 20m

Step-by-step explanation:

given,

rate of turfing a triangular field is rs. 45 per 100msq. is rs. 900.

therefore area of the triangle is -

=>900/45*100

=>2000msq.

given,

base of the triangle is 2.5 times of the height!

therefore let the height be x!

now,

area of a triangle = 1/2*base*height

=> 2000m =1/2*2.5x*x

=> 2000m =1/2*x*25/10x

=> 2000m. =x/2*25x/10

=> 2000m. =25xsq. /20

=> 2000*20/25. = x^2

=> 160msq. = x^2

=> √160=x

=> 40 = x

therefore the height of the triangle is 40m.
