Question

Find thecost of fencing a rectangular park of length 175 m and breadth 125 mat the rate of Rs 12 per metre.

Answer 1

Length (l)of rectangular park = 175 m

Breadth(b) of rectangular park = 125 m

Length ofwire required for fencing the park = Perimeter of the park

= 2 × (l + b)

= 2 × (175 + 125)

= 2 × 300

= 600 m

Cost forfencing 1 m of the park = Rs 12

Cost forfencing 600 m of the square park = 600 × 12

= Rs 7200
