Question

The sides triangle field are 41m ,40m,9m .Find the number of rose beds that can be prepared in the field ,if each rose bed on an average needs 900cm2 space

Answer 1

s=(41+40+9)/2
=90/2
=45
area=√s(s-a)(s-b)(s-c)
=√45*4*5*36
=30*6
=180 sq m
No of rose beds=(180*100*100)/900
=2000

Answer 2

Answer:

s=(41+40+9)/2

=90/2

=45

Area={s(s-a)(s-b)(s-c)}^1/2

=( 45×4×5×36)^1/2

=30×6

=180sq.m

No.of rose=(180×100×100)/900

=2000
