(a+b)(a-b) = a² - b²
We have rectangular piece of land measuring 107 × 103
by using identity
(105 + 2) (105 - 2) = 105² - 2²
11025 - 4
11021
so the area of land = 11021 m²
the amount he will have to pay = 11021 × 22
Rs. 242462

Length = 107 m
Breadth = 103 m
so,by using the (a+b)(a-b) = (a² - b²)
=(105+2)(105-2) = (105² - 2²)
= 11025 - 4
so the area = 11021 m²
now,
per m² =Rs. 22
so for 11021 m² = 22 * 11021
= Rs. 242462
Breadth = 103 m
so,by using the (a+b)(a-b) = (a² - b²)
=(105+2)(105-2) = (105² - 2²)
= 11025 - 4
so the area = 11021 m²
now,
per m² =Rs. 22
so for 11021 m² = 22 * 11021
= Rs. 242462
