(a) The length of the fencing required
(b) Total cost of the fencing, if the one meter fencing cost Rs 10

Answer 1

Answer:

Here's your answer

Step-by-step explanation:

We take perimeter

We use unitary method. That's very convenient to use in such Questions.

Answer 2

Answer:

Since its fencing we have to find the perimeter.

l=200m

b=120m

P= 2 × [ l + b]

 = 2 × [ 200+ 120] = 2 × 320 = ×640m

(a) Therefore the length for the fencing = 640m

(b) 1m = Rs 10

     640m = 640 × 10 = Rs 6400

Hope this helps...
