Question

What is the cost of tiling a rectangular plot of land 500 m long and 200 m wide at the rate of Rs 8 per hundred sq m.?

Answer 1

Area of rectangular plot

= l × b

= 500 × 200

= 100000 m²

Cost of tiling the rectangular plot of land = (100000 / 100) × 8

= 1000 × 8 = 8000

∴ Cost of tiling the rectangular plot of land is ₹8000.

Answer 2

$\textsf{Length of land = 500 m}$



$\textsf{Breadth of land = 200 m}$



$\textsf{Area of land = length x breadth}$
$\: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \textsf{= 500 m x 200 m}$
$\: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: {= 1,00,000 \: m}^{2}$



°•° $\textsf{Cost of tiling 100 sq. m of land}$ = ₹ 8



•°• $\textsf{Cost of tiling 1,00,000 sq. m of land}$$\textsf{= 8 x 100000/100 = 8000}$

Therefore, cost of tiling a rectangular plot is ₹ 8000
