Question

Find the cost of fencing a rectangular park 300 m long and 200 m wide at the rate of ₹4 per metre.

Answer 1

Length of the park = 300 m

Breadth = 200 m

$\therefore$ Perimeter of the park = 2 [length + breadth]

= 2 [300 m + 200 m]

= 2 $\times$ 500 m = 1000 m.

Cost of fencing the rectangular park = 1000 $\times$ 4 = ₹4000
