Answer 2

Answer:

1) Breadth = 25 m and Perimeter= 130 m

2) Cost=94500 rupees

Step-by-step explanation:

Given : The area of a rectangular garden of length 40m, is 1000 sqm.

The garden is to be enclosed by 3 rounds of fencing, leaving an entrance of 4 m.

To find :

1) The breadth of the garden and its perimeter.

2) The cost of fencing the garden at a rate of 250 rupees per metre.

Solution :

1) We have given,

Area=A=1000 m²

length=l=40m

breadth=b=?

A=l×b

1000/40=b

25=b

Breadth =25m

Perimeter of the garden,

P=2(l+b)

P=2(40+25)

P=2×65

Perimeter =130 m

2) Total fence is required to fence 3 times rectangular garden is

=130×3

=390 m

Now, leaving an entrance total 4m×3=12m

Required fence is =390-12 =378m

The cost of total fence is

C=378×250

C=94500 rupees
