Solution

Transcript

Solution:

Length of rectangular park = 175 m

Breadth of rectangular park = 125 m

Perimeter of park = 2 x (length + breadth)

= 2 x (175 + 125)

= 2 x 300 = 600 m

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

Therefore, cost of fencing park of 600 m = 12 x 600 = Rs. 7,200

Answer 2

Step-by-step explanation:

Perimeter of Rectangle = 2 ( l + b )

= 2 ( 150+100)

= 2(250)

= 500 m.

Cost = 500 × 30

= ₹ 15000 Ans.
