Answer 1

Answer:

length=250

cost =₹135000

Answer 2

Answer:

Given ;

Perimeter = 900 m

Breadth = 200 m

Therefore ; we know

2(b + l) = perimeter ( for rectangle )

2(200 + l ) = 900

200 + l = 900/2

200 + l = 450

l = 450 - 200

l = 250 .... (i) [ Answer ]

now

total cost of fencing the park = 150 × 900 = Rs.135000
