Ex 11.1, 1 The length and the 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.
Length of rectangle land = l = 500 m
Breadth of rectangle land = b = 300 m
Now,
Area of land = l × b
= 500 × 300
= 1,50,000 sq. m.
= 1,50,000 m2
Now,
Cost of 1 m2 of land = Rs 10,000
Cost of 1,50,000 m2 of land = Rs 10,000 × 1,50,000
= Rs 1,50,00,00,000
