Chemical weathering is when chemicals in rain and moving water react with rocks and minerals to change or weaken them in some way. Chemical weathering always causes some type of chemical reaction within the rock or mineral itself. Expand your knowledge of the breaking down of rocks and soil through examples of erosion.

Step-by-step explanation:
From the question it is given that,
Length of the rectangular piece of land = 500 m
Breadth of the rectangular piece of land = 300 m
Then,
(i) Area of rectangle = Length × Breadth
= 500 × 300
= 150000 m2
(ii) Cost of the land for 1 m2 = ₹ 10000
Cost of the land for 150000 m2 = 10000 × 150000
= ₹ 1500000000
