Question

Find the cost of fencing a rectangular park of length 180m and breadth 130m at the rate of Rs 12 per meter

Answer 1

I think may be like this mate

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

• Length of rectangular park = 180 m

• Breadth of rectangular park = 130 m

• Rate of fencing = Rs. 12

__________ [ GIVEN ]

• We have to find the cost of fencing the rectangular park.

____________________________

» We know that

Perimeter of rectangle = 2(length + breadth)

→ 2(180 + 130)

→ 2(310)

→ 620 m

_____________________________

From above calculations we have Perimeter of rectangle is 620 m

So,

Cost of fencing the rectangular park = 12 × Perimeter of rectangle

→ 12 × 620

→ 7440

_____________________________

Rs. 7440 is the cost of fencing the rectangular park.
