Question

1. 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

Answer:

Hii sis

Answer ⤵️

Here,

1.i) L(Length)=500m

B(Breadth)=300m

Area of a rectangular land = 2(l+b)

Area of a rectangular land= 2(500+300)

Area of a rectangular land= 2×800

Area of a rectangular land= 1600 m².

ii) 1m² costs ₹10000

So how much 1600 m² costs= 1600×10000

Total cost= 16,000,000

Answer 2

$\large{\underline{\underline{\pmb{\red{\sf{ \: Given :- }}}}}}$

• The length and breadth of a rectangular piece of land is 500 m and 300 m, respectively.

$\rule{200pt}{3pt}$

$\large{\underline{\underline{\pmb{\blue{\sf{ \: To \: Find :- }}}}}}$

• Area of the land and Cost of land if 1m² costs ₹ 10000 .

$\rule{200pt}{3pt}$

$\large{\underline{\underline{\pmb{\orange{\sf{ \: Solution :- }}}}}}$

$\color{maroon}{✪}$Formula Used :

$\large{\color{blue}{\bigstar}} \: \: {\underline{\boxed{\red{\sf{ Area{\small_{(Rectangle) }} = Length \times Breadth }}}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━}$

$\color{maroon}{✪}$Calculating the Area :

${:\implies{\qquad{\sf{ Area{\small_{(Land) }} = Length \times Breadth }}}} \\ \\ \ {:\implies{\qquad{\sf{ Area{\small_{(Land) }} = 500 \times 300 }}}} \\ \\ \ {\qquad{\textsf{ Area of piece of land = {\green{\sf{ 150000 \: m² }}}}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━}$

$\color{maroon}{✪}$Calculating the Cost :

${\longmapsto{\qquad{\sf{ Cost{\small_{(Land) }} = Area \times Rate }}}} \\ \\ \ {\longmapsto{\qquad{\sf{ Cost{\small_{(Land) }} = 150000 \times 10000 }}}} \\ \\ \ {\qquad{\textsf{ Cost of piece of land = {\pink{\sf{ ₹ \: 1500000000 }}}}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━}$

Therefore :

❝ Cost of the piece of land is ₹ 1500000000 . ❞
