Answer 1

Step-by-step explanation:

Length=50 CM

Breadth=40 CM

Area of rectangle= l×b=50×40

=1200 cm^2

=12 m^2

Total cost = 12×10000

=₹120000

Answer 2

Step-by-step explanation:

$rectangle \: area \: =l \times b \\ = 50 \times 40 \\ = 2000 \: sq.cm \\ \\ 1 {m}^{2} = rs.10000 \\ 2000 \times 10000 = 20000000 \\ \\ hence \: the \: price \: is \: rs.20000000$
