Answer 2

Given :-

• Area of the square plot = 60025m²
• The rate of fencing the for 1m² = Rs.50

To Find :-

• The cost of fencing the total plot.

Solution :-

• In order to find the cost of fencing the plot we need to find the perimeter of the plot.

• Area of the plot = 60025m²

• Area of the square = (Length of square)²

• Area of the plot = (Length of the plot)²

$\sf\rightarrow \: Length \: of \: the \: plot = \sqrt{Area}$

$\sf\rightarrow \sqrt{60025}$

$\sf\rightarrow245$

∴ Length of the plot = 245m

• Now perimeter of the plot:-

Perimeter of the plot

=> 4 × 245

=> 980

∴ Perimeter of the plot = 980m

• Cost of fencing for 1m² = Rs.50

• Cost of fencing 980m² = 50 × 980 = Rs.49,000

Cost of fencing the field = Rs.49000
