Question

Find the cost of fencing a square park of side $360m$ at the rate of $₹15$ per metre.

Answer 1

STEP 1 : Finding the perimeter of the square park

Side of the square park $=360m$
Perimeter of the square park $=4\times \mathrm{side}$

$=4\times 360$

$=1440m$

STEP 2 : Finding the cost of fencing the square park

Rate of fencing per metre $=₹15$

Cost of fencing the square park $=\mathrm{Perimeter}\times \mathrm{Rate}$

$=1440\times 15$

$=₹21,600$

Hence, the cost of fencing the square park is $₹21,600$.
