1.	the length and the breadth of a rectangular piece of land are 400m and 250m respectively. what is the cost of the land at ₹1000per square metre
Answer» The COST of the land at Rs. 1000 PER m² = Rs. 100000000. Given : The length of a rectangular piece = 400 m. The BREADTH of a rectangular piece = 250 m. To Find : The cost of the land at Rs. 1000 per m². Solution : 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, $\huge{ \blue{ \bf{ \star}}} \: \: \large \boxed{ \pink{ \bf{A = l \times b}}}$ 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. $\bf \implies 400 \: m \times 250 \: m \\ \\ \\ \bf \implies 100000 \: {m}^{2}$ 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. $\bf \implies Rs. \: 1000 \times 100000 \\ \\ \\ \bf \implies Rs. \: 100000000$ Hence, The cost of the land at Rs. 1000 per m² is Rs. 100000000.

the length and the breadth of a rectangular piece of land are 400m and 250m respectively. what is the cost of the land at ₹1000per square metre

Answer»

Given :

To Find :

Solution :

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,

$\huge{ \blue{ \bf{ \star}}} \: \: \large \boxed{ \pink{ \bf{A = l \times b}}}$

Where,

We have,

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

$\bf \implies 400 \: m \times 250 \: m \\ \\ \\ \bf \implies 100000 \: {m}^{2}$

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.

$\bf \implies Rs. \: 1000 \times 100000 \\ \\ \\ \bf \implies Rs. \: 100000000$

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