Answer 1

Answer:

i don't know sorry I really don't know maam

Answer 2

Step-by-step explanation:

here, a=120m,

b=80m,

c=50m

and, s= a+b+c/2

= 250/2

=125

Area 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
