Question

what is the cost of tilting a rectangular plot of land 500m long and 200m wide at the rate of rupee 8 per hundred sq.m?​

Answer 1

Answer:

Cost of tiling the rectangular plot

= Rs (8/100)m² × Area of rectangle

=Rs (8/100)m² × (l× b)

= Rs (8/100)m² × 500m × 200m

= Rs 8 × 1000

= Rs 8000

Answer 2

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

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

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

$\sf{ \green{\therefore \: Area \: \: of \: \: the \: \: rectangular \: \: plot = l \times b }} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{ \green{= ( 500 \times 200) \: m {}^{2} }} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf{\green{= 100000 \: m {}^{2} }}$
