Question

The length of a playground is 36m and breadth is 24m.Find tge cost of leveling it at the rate of Rs.125 per sq meter.Also find the cost of fencing it at the rate of Rs.100 per meter​

Answer 1

Answer:

12000 rupees

Step-by-step explanation:

area of playground= 36×24

=864m^2

cost=864×125

=108000rs

perimeter=2(36+24)

=2(60)

=120m

cost of fencing=120×100

=12000 rps

Answer 2

Given : -

The length of a playground is 36 meters and breadth of a playground is 24 meters .

Required to find : -

• Cost of fencing the whole playground ?

• Cost of leveling the whole playground ?

Formulae used : -

$\boxed{\begin{minipage}{8cm} \\ \sf{ Area of the rectangle = length \times Breadth } \\ \\ \sf{ Perimeter of the rectangle = 2 ( length + breadth )} \end{minipage}}$

Solution : -

The length of a playground is 36 meters and breadth of a playground is 24 meters .

So,

Length of the playground = 36 meters

Breadth of the playground = 24 meters

Now,

we need to find the cost of fencing the whole playground .

Here,

we need to apply a bit of logic .

As we know that ,

The fencing will be done along the boundaries .

So,

Perimeter of the rectangle = Sum of all its boundaries .

Here,

Finding the perimeter of the rectangle helps us to find the cost of fencing .

Using the formula ;

Perimeter of the rectangle = 2 ( length + breadth )

=> Perimeter = 2 ( 36 + 24 )

=> Perimeter = 2 ( 60 )

=> Perimeter = 120 meters

Hence,

Amount of measurement needed to be fenced is 120 meters

Cost of fencing 1 meter = Rs. 100

Cost of fencing 120 meters = ?

This implies ;

=> 120 x 100

=> Rs. 12,000

Similarly,

Now,

Let's try to find out the cost of leveling the playground.

Since,

with a basic logic we can say that the leveling is done for the area .

So,

Let's find the area of the playground ;

Using the formula ,

Area of the rectangle = length x breadth

=> Area of the rectangle = 36 x 24

=> Area of the rectangle = 864 m²

Hence,

Amount of area needed to be levelled is 864 m²

Cost of leveling per m² = Rs. 125

Cost of leveling 864 m² = ?

This implies ;

=> 864 x 125

=> Rs. 1,08,000

Therefore,

Cost of leveling the playground = Rs. 1,08,000

Cost of fencing the playground = Rs. 12,000
