Question

The length and breadth of a playground are 80m and 35m respectively find the coat of levelling it at rs 450 per square metre

Answer 1

Answer:

1260000

Step-by-step explanation:

Area=35x80=2800

Cost of levelling=2800x450=1260000

Answer 2

Answer :-

• The cost of leveling the playground is Rs 1260000.

Given :-

• The length and breadth of a playground are 80 m and 35 m respectively.

To find :-

• The cost of leveling it at Rs 450 per square metre.

Step-by-step explanation :-

• In this question, the length and breadth of a playground has been given to us. It has also been given that the cost of leveling it is Rs 450 per square metre. We have to find the cost of leveling the whole playground. For this, we are going to find the area of the playground and not the perimeter, because leveling can only be done inside the playground. We are going to use the formula required for finding the area of a rectangle because it's a rectangular playground. Let's find out our answer now!

Calculations :-

We know that :-

$\underline{\boxed{ \sf Area \: \: of \: a \: rectangle = Length \times Breadth}}$

Here,

• Length = 80 m.
• Breadth = 35 m.

Hence,

$\boxed{ \tt Area \: of \: the \: playground = 80 \times 35}$

Multiplying the numbers,

$\underline{ \boxed{ \tt Area \: of \: the \: playground = 2800 \: m^2}}$

• Therefore, the area of the playground is 2800 m².

------------------------------

• Now let's find the cost of leveling it at the rate of Rs 450 per square metre.

• It has been given that for every square metre, the cost of leveling is Rs 450.

• So, for leveling 2800 square metre, the cost is :-

$\underline{\boxed{ \tt450 \times 2800 = Rs \: 1260000.}}$

------------------------------

• Hence, the cost of leveling the playground at the rate of Rs 450 per square metre is Rs 1260000.
