Question

Find the cost of fencing a rectangular park of length of 10 m and
breadth of 5 m at the rate of Rs 10 per metre.
Rs 300
Ps 600
Rs150
Rs1200​

Answer 1

GIVEN,

breadth = 5m

length = 10m

cost of fencing per metre = rs.10

To find the total cost of fencing the park, we first have to find it's perimeter.

Perimeter = 2(l+b)

l = length

b = breadth.

hence,

perimeter = 2(10+5)

= 2(15)

= 30 m

If cost of fencing 1 metre is rs.10 then the cost of fencing 30 metres will be: 30×10 = rs.300

therefore, the correct answer is option (a)rs.300

hope it helps

have a great day.
