Question

thre is tringular field with the length of the sides 200m,210m,and 290. find the cost of rising the lawan in that plot at the rate of rupees 5/m^2

Answer 1

Step-by-step explanation:

As we are knowing,

lengths of three sides are=200,210,290m

Perimeter=200+210+290

=700m

By Heron's formula,

SEMI-PERIMETR=700/2=350m2

=s(s-a) (s-b) (s-c)

=350(350-200)(350-210)(350-290)

=350×150×140×60

=441000000m sq.

Hence, 1 m sq. =₹5

,441000000 m sq. =441000000×5

=₹2,20,50,00,000
