Question

The cost of fencing Rectangular park of length 10m and breadth 5m at the rate of rs10 per metre is

Answer 1

Answer:

Rs. 300

Step-by-step explanation:

• length = 10 m
• breadth = 5 m

perimeter = 2 ( l + b )

= 2 ( 10 + 5 )

= 2 ( 15 )

= 30 m

Cost of fencing 1 metre = Rs. 10

Cost of fencing 30 metres = 10 x 30

= Rs. 300

Answer 2

Given:

Rectangular park of length 10m and breadth 5m

To Find:

The cost of fencing at the rate of rs10 per metre is

Solution:

It is given that the park has a dimension of 10m*5m and we need to find the cost of fencing at the rate of Rs10/m, first, we need to find the perimeter of the rectangular park which can be found by using the formula,

Perimeter=2(L+B)

where,

          L= length

          B= breadth

so put the values to get the measure of the perimeter which is,

Perimeter= 2(10+5)

                =30m

Now the cost of fencing will be,

Cost= 30m*Rs10/m

      =Rs300

Hence, the cost of fencing the rectangular park is Rs 300.
