A) Rs.2671
B) Rs.4401
C) Rs.2512
D) Rs.3140
Correct Answer: D
Solution :
\[AB=40\text{ }m\] and radius of semicircular plot \[=\frac{40}{2}=20\,m\] Area of 4 circular plots \[=4\times \] (Area of semi circle) \[=4\times \frac{1}{2}\times \pi \times {{20}^{2}}\] \[=2\times 3.14\times 400=2512\,{{m}^{2}}\] Cost of turfing the plots at the rate Rs.1.25 per sq. \[m=2512\times 1.25=Rs.3140\]You need to login to perform this action.
