Question

The length and breadth of a rectangular land are 400m and 250m
respectively. What is the cost of the land at Rs 1000 per sq metre?​

Answer 1

Answer:

Step-by-step explanation:

We have to find the cost of the land at Rs. 1000 per m².

So, for finding the cost of the land at Rs. 1000 per m².

First we need to find the are of a rectangular piece.

We know that,

Where,

Area is denoted with A.

Length is denoted with l.

Breadth is denoted with b.

We have,

l = 400 m.

b = 250 m.

Now, substitute both the given values in the formula of the area of the rectangle.

Hence, the area of a rectangular park is 100000 m².

Now, we can find the cost of the land at Rs. 1000 per m².

Cost of 1 m² of land = Rs. 1000

Here we have to find the cost of 100000 m² of land.

Hence,

The cost of the land at Rs. 1000 per m² is Rs. 100000000.

Answer 2

The cost of the land at Rs. 1000 per m² = Rs. 100000000.

Given :

• Length of a rectangular piece = 400 m.
• Breadth of a rectangular piece = 250 m.

Have to Find :

• The cost of the land at Rs. 1000 per m².

Solution :

Let's find out area of the land first

We know that,

It is in rectangular shape then,

Area = l ×b

Here,

Length = " l "

Breadth = " b "

Now, substitute both the values in the above formula.

A = 400 × 250

A = 100000m²

We now have , area of a rectangular park is 100000 m².

According to the Question

Cost of 1 m² of land = Rs. 1000

So, the cost of the rectangular piece = Area × Cost

100000 × 1000

= 100000000 Rs.

Therefore,

The cost of the land at Rs. 1000 per m² is Rs. 100000000.
