Question

the lengths and the breadth of a rectangular piece of land are 500m and 300m respectively. find
(I) it's area (ii) the cost of land ,if 1m2 of the land costs rupees 10,000​

Answer 1

Answer:

(i) length = 500m

breadth = 300m

area = l x b

500 x 300

= 150000m^2

(ii) cost = 150000 x 10000 = Rs 1500000000

Answer 2

ANSWER:

• (i) The area = 1,50,000 m².

• (ii) The cost of land = ₹ 1,50,00,00,000.

GIVEN:

• Length and the breadth of a rectangular piece of land are 500 m and 300 m respectively.

• 1 m² of the land costs ₹ 10,000.

TO FIND:

• (i) The area.

• (ii) The cost of the land.

EXPLANATION:

$\boxed{ \bold{ \large{ \gray{Area\ of\ rectangle = l \times b}}}}$

Length = 500 m

Breadth = 300 m

Area = 500 × 300

Area = 1,50,000 m²

Hence the area of the rectangle = 1,50,000 m²

1 m² of the land costs ₹ 10,000.

1,50,000 m² = 1,50,000 × 10,000

1,50,000 m² = ₹ 1,50,00,00,000

Hence the land costs ₹ 1,50,00,00,000.

ADDITIONAL INFORMATION:

$\boxed{ \bold{ \large{ \gray{Perimeter \ of \ rectangle=2( l + b)}}}}$

Length = 500 m

Breadth = 300 m

Perimeter = 2(500 + 300)

Perimeter = 2(800)

Perimeter = 1600 m.

Hence perimeter = 1600 m.
