Answer 1

Answer:

Step-by-step explanation:

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

Find:

(i) Its area.               (ii) The cost of the land, if 1 m2 of the land costs Rs 10,000.

Answer:

Given: Length of a rectangular piece of land = 500 m

and breadth of a rectangular piece of land = 300 m

(i) Area of a rectangular piece of land = Length * Breadth

                                                                  = 500 * 300

                                                                  = 1,50,000 m2

(ii) Since, the cost of 1 m2 land = Rs 10,000

Therefore, the cost of 1,50,000 m2 land = 10,000 * 1,50,000  = Rs 1,50,00,00,000
