Question

The Length and the breadth of a rectangular piece of land are 500 m and 300 m, respectively. Find

(i) Its area (ii) the cost of the land, if 1 m2 of the land costs ₹ 10,000.

Answer 1

$\huge{ \bold{ \color{orange}{❥a᭄nswer}}}$

$\rm {\color{grey} {\overline{ \underline{|given|}}}}$

• Length of rectangular plot= 500m
• Breadth of rectangular plot= 300m

$\rm{ \color{grey}{ \overline{ \underline{ |to \: find|}}}}$

• Area of rectangular plot
• Cost of rectangular plot at the rate of ₹10,000 per $\rm {m}^{2}$

$\rm{ \color{grey}{ \overline{ \underline{ |solution| }}}}$

Area of rectangle = length×breadth

= 500m×300m

$\rm = 150000 {m}^{2}$

$\rm{cost \: of \: 1 {m}^{2} \: land =₹10000 }$

$\rm{cost \: of \: 150000 {m}^{2} \: land = 150000 \times 10000}$

$\rm{ =₹1500000000 }$

Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• Here, we have to find the Area of the Rectangular field. To find the Area, we have to use the formula of :

$\boxed{\sf Area \: of \: Rectangle = l \times b}$

• After, we find the Area. We have to multiply the Area with the Cost.

Given :

• Length = 500 m
• Breadth = 300 m
• Cost = ₹ 10,000

To find :

• Its area
• The cost of the land

Solution :

Area of Rectangular Field = l × b

                                           = 500 × 300 m²

                                           = 150000 m²

∴ Area of Rectangular Field is 150000 m².

Cost of Land = Area × Rate

                     = 150000 × 10,000

                     =  ₹ 1500000000

∴ Cost of Land is ₹ 1500000000.
