Question

What is rhe cost of tiling of a rectangular plot of land 500m long and 200m wide at the rate of rupees 8per hundred square metre

Answer 1

$\huge \color{red} \mathfrak Answer :-$

Length = 500 m

Breadth = 200 m

Area = l × b

= 500 × 200 = 100000 m^2

Cost of tiling 100m^2 = Rs 8

Cost of tiling 1 m^2

= 8 /100

Cost of tiling 100000 m^2

= 8/100 × 100000

= 8 × 1000

= Rs . 8000

Answer 2

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: SOLUTION\: \: } \mid}}}}}$

$\underline{ \mathfrak{ \: Given, \: }} \\ \\ \text{ \pink{Length of the rectangular plot, l = 500 m}} \\ \\ \text{ \pink{Breadth of the rectangular plot, b = 200 m}} \\ \\ \text{ \pink{Cost of tiling 100 m = Rs. 8 }}\\ \\ \underline{ \mathfrak {\: To \: \: find : \to}} \\ \\ \text{ \pink{ Cost of tiling the whole rectangular plot = ? }}$

$\underline{ \mathfrak{ \: We \: \: know \: \: that, \: }} \\ \\ \boxed{ \bold{ \: \: </p><p>Area \: \: of \: \: a \: \: rectangle = Length \times Breadth \: \: }}$
