Answer 1

Answer:

plantation area=1452.36 sq.mtr

fencing cost=₹ 4940/-

Step-by-step explanation:

sides are

120m, 80m and 50 MTR

for plantation we need to calculate area of triangle

using Heron's formula

A method for calculating the area of a triangle when you know the lengths of all three sides.

Let a,b,c be the lengths of the sides of a triangle. The area is given by:

Area = √ p ( p − a ) ( p − b ) ( p − c )

where p is half the perimeter,

1452.3688 sq.me

for fencing

perimeter=side+side+side

=120+80+50

=250 mtr

but leave 3 mtr for gate

i.e.250-3=247

then 20 rs per meter

247*20= ₹4940 is the cost for fencing
