Answer 1

$\huge\underline\mathfrak\blue{\:♡Solution\:♡}$

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

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 = 1,50,000 m2

Answer 2

Answer:

$\underline\green{ɢɪᴠᴇɴ:}$

Length of a rectangular piece of land = 500 m

and breadth of a rectangular piece of land = 300 m

$\underline\red{Şᴏʟᴜᴛɪᴏɴ:}$

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

= 500 × 300

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

$\underline\green{ᴛʜᴇʀᴇғᴏʀᴇ, }$

The cost of 1,50,000 m² land = 10,0

00 × 1,50,000 = Rs 1,50,00,00,000 = 1,50,000 m²
