Question

the length of a rectangle is 130 metre and the breadth is 95 respectively find the cost of fencing the field at rupees 20 per metre​

Answer 1

Answer:

Given:

Length of a rectangle(l)=130 m

Breadth of a rectangle(b)=95 m

For fencing we have to find the perimeter because fencing is only done on the border.So ,

We have,

Perimeter of field =2(l+b)

=2(130+95)

=2 *225 m

= 450 m

Now, cost for fencing

So,cost of 450m= 450 * Rs.20

= Rs.9000

Hence,the total cost for fencing the field is Rs.9000.

Answer 2

Step-by-step explanation:

l=130m

b=95

fencing is only done on the border

so we have to find perimeter

2(l+b)

2×(130+95)

225×2

450m

we have to fence 450m

1 metre =20rs

so fencing cost

450×20rs

9000rs
