Question

1)Find the cost of fencing a rectangular park of length 175m and breadth 125m at the rate of 12/Rs per metre.

2)Find the cost of fencing a square park of side 250m at the rate of 20/Rs per metre.

Answer 1

Explanation:

Length of rectangular park = 175 m

Breadth of rectangular park = 150 m

Perimeter of park = 2 x (length + breadth)

= 2 x (175 + 150)

= 2 x 325 = 650 m

Since, cost of fencing park per meter = = Rs. 12

Therefore, cost of fencing park of 600 m = 12 x 650 = Rs. 7,800

Square park=250m

Perimeter of the square park x 4

=250x4

=1000m

So, the cost of the fencing at the park would have a rate of 20 per m = 1000x20

=20000
