The side of a square field is $120$ meters. The cost of preparing a grass lawn is $Rs.35$ per square meter. How much will it cost, if the entire field is converted into a lawn?

• A. $Rs.404000$
• B. $Rs.504000$
• C. $Rs.506000$
• D. $Rs.500000$

Answer 1

The correct option is B $Rs.504000$

Area of square field $=sid{e}^2=(120m{)}^2=14400m^2$

cost of preparing a grass lawn $=Rs35/m^2$

Total cost $=14400\times 35Rs$

$=Rs5,04,000$
