Find the cost of fencing a square park of side 250 m at the rate of ` 20 per metre. TIPS To find the cost of fencing, multiply the perimeter of square (\[4\times \] length of side) by rate of fencing.

Answer:

Given, side of square park = 250 m Then, the perimeter of square park \[=4\times \] Length of side of park \[=4\times 250m=1000m\] Cost of fencing per metre = ` 20 \[\therefore \] Cost of fencing 2000m \[=1000\times 20\]= ` 20000 Hence, the cost of fencing a square park is ` 20000.
