• A. $Rs.17,875$
• B. $Rs.17,675$
• C. $Rs.12,875$
• D. $Rs.17,825$

Answer 1

Answer: (A)

$Rs.17,875$

Area of the garden = Area of the outer square - Area of the inner rectangle
$=25\times 25m^2-20\times 15m^2$
$=(625-300)m^2=325m^2$
Cost of developing a garden @ $Rs.55per{m}^2=Rs.(55\times 325)=Rs.17,875$.
