Find the cost of fencing a rectangular park of length 175 m and breadth 125 m at the rate of ` 12 per metre. TIPS To find the cost of fencing a rectangular park, multiply its perimeter [2 (length + Breadth)] by rate of fencing.

Answer:

Given, length of rectangular park = 175 m and breadth of rectangular park = 125 m Then, the perimeter of rectangular park = 2 (Length + Breadth) \[=2(175+125)m=2\times 300cm=600m\] Cost of fencing per metre = ` 12 \[\therefore \] Cost of fencing 600 m = 600 x 12 = ` 7200 Hence, the cost of fencing a rectangular park is ` 7200.
