here, a=120m,

here, a=120m,b=80m,

here, a=120m,b=80m,c=50m

here, a=120m,b=80m,c=50mand, s=

here, a=120m,b=80m,c=50mand, s= 2

here, a=120m,b=80m,c=50mand, s= 2a+b+c

here, a=120m,b=80m,c=50mand, s= 2a+b+c =

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass =

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c)

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) =

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) = 125(125−120)(125−80)(125−50)

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) = 125(125−120)(125−80)(125−50) =375

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) = 125(125−120)(125−80)(125−50) =375 15

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) = 125(125−120)(125−80)(125−50) =375 15 m

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) = 125(125−120)(125−80)(125−50) =375 15 m 2

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) = 125(125−120)(125−80)(125−50) =375 15 m 2 cost of fencing =[(a+b+c)−3].20

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) = 125(125−120)(125−80)(125−50) =375 15 m 2 cost of fencing =[(a+b+c)−3].20=[250−3].20

here, a=120m,b=80m,c=50mand, s= 2a+b+c = 2250 =125Area she need to plant grass = s(s−a)(s−b)(s−c) = 125(125−120)(125−80)(125−50) =375 15 m 2 cost of fencing =[(a+b+c)−3].20=[250−3].20=Rs4940
