Question

Find the cost of fencing a rectangular park of length 10 m and breadth 5 m at the rate of? 10 per metre
​

Answer 1

Answer:

₹ 300

Step-by-step explanation:

Perimeter of rectangle = 2 x ( L + B )

= 2 x ( 10 + 5 )

= 2 x 15

= 30 m

If cost 10 per metre

then ,

cost of 30 m =30 x 10

= ₹ 300

Answer 2

Answer:

Rs. 300

Step-by-step explanation:

Firstly we need to find the perimeter/boundary(P) of the park.

P = 2*(l + b)

P = 2*(10 + 5)

  = 2*15

  = 30

So, if the cost of fencing the park is Rs. 10 per metre, then,

the total cost is 10*30

Total Cost = Rs.300
