to find no. of rosebeds we need area of triangular field.. =herons formula
√s(s-a) (s-b) (s-c)
a+b+c/2=s
41+40+9/2
=45
√45(45-41)(45-40)(45-9)
√45*4*5*36
√5*3*3*2*2*5*6*6
2*5*3*6=180cm^2
no. of rosebeds= area of field/area of each rosebuds.
√s(s-a) (s-b) (s-c)

41+40+9/2
=45
√45(45-41)(45-40)(45-9)
√45*4*5*36
√5*3*3*2*2*5*6*6
2*5*3*6=180cm^2
no. of rosebeds= area of field/area of each rosebuds.

sorry but not a Hindi question
answer-
by applying heron's formula
s=41+9+40/2=45
area of triangle
=√(45)(45-9)(45-40)(45-41)
√(45)(36)(5)(4)
√(45)(36)(20)
√(45*4)²
45*4=180cm²
I think ques has some mistake . each flower
bed must have 90 cm² area
then 2 such flower beds could be made .
hope it helps.
