Question

The length and breadth of a rectangular piece or land are 500m and 300m respectively.

Find its area and the cost of land if m²

of land costs Rs. 10,000/​

Answer 1

We have ,

Length of land = 500m

Breadth of Land = 300m

1) Perimeter = 2(l+b)

= 2 (500+300)m

= 2 × 800 meter.

Perimeter = 1600m

2) Area of land = (l × b)

= (500 × 300)m sq.

= 150000 m sq.

3) The cost of 1m sq. of land = 10,000

The cost of 150000m sq. of land = 10,000 × 150000

= rs. 1500000000

Answer 2

Given: Length of a rectangular piece of land

=

500

m

and Breadth of a rectangular piece of land

=

300

m

Area of a rectangular piece of land =Length×Breadth

=

500×

300=

1,50,000m

2

Since, the cost of 1m

2

land = Rs 10,000

∴, the cost of 1,50,000m

2

land

=

10,000×

1,50,000=

Rs

1,50,00,00,000
