Question

a rectangular field 80m by 45m if fencing costs ₹85.40 per meter​

Answer 1

Answer:

perimeter = 2 ( l + b )

= 2( 80+45)

= 2( 125)

= 250m

now, cost of 1 m = 85.4

so, cost of 250m = 250 × 85.4

= 21350₹

Answer 2

Answer:

21,350/-

Step-by-step explanation:

as we know the perimeter of a

rectangle is:-2(l+b)

Now ,length=80m

breadth=45m

therefore,perimeter= 2(80+45)

=) 2(125)

=)250

if 1m costs 85.40/-

then,250 m = 85.40×250

=)21,350/-
