The length and the breadth of a rectangular piece of land is 500 m and 300 m respectively. Find (i) its area (ii) the cost of the land, if 1 \[{{\text{m}}^{\text{2}}}\] of the land cost  ` 10,000.

Answer:

                (i) Area of the rectangular piece \[=\text{Length}\times \text{Breadth}\] \[=\text{5}00\times \text{3}00{{\text{m}}^{\text{2}}}\] \[=15000\text{0 }{{\text{m}}^{\text{2}}}\] (ii) \[\because \]              \[1\,{{m}^{2}}\] of the land costs = ` 10000 \[\because \]     \[150000\,{{m}^{2}}\] of the land costs = ` \[\text{1}0000\times \text{15}0000\]                 = ` 1500000000.
