Question

find the cost of fencing a rectangle park of length 300m and breath 200 m at the rate of rs 24 per metre

Answer 1

perimeter of the rectangle park = 2 (length + bredth)
=2 (300m + 200m )
=2×500
=1km
=1000m
cost = 1000×24=24000rs.

Answer 2

Given:

The length of the park=300m

The breadth of the park=200m

Rate=Rs.24/m

To find:

The cost of fencing the park

Solution:

The cost of fencing the park is Rs.24,000.

We can find the cost by following the given steps-

We know that the fencing is done only on the outer edges of the park i.e., the perimeter of the park.

Since the park is rectangular, the perimeter of the park will be twice the sum of its length and breadth.

We are given that the length of the park=300m

The breadth of the park=200m

So, the perimeter of the park=2(Length+Breadth)

On putting the values,

The perimeter of the park=2(300+200)

=2(500)

=1000 m

Now, the cost of fencing the park=Rate of fencing×Perimeter of the park

The rate of fencing the park=Rs.24/m

The cost of fencing=24×1000

=Rs.24,000

Therefore, the cost of fencing the park is Rs.24,000.
