Question

The length of a rectangular piece of land is 350m and its breadth is 200 m. Find . Perimeter and cost of fencing it three times with a wire at the rate of rupees 5 per metre

Answer 1

Answer:

Length = 350 m

Breadth = 200 m

Perimeter = 350 × 200

= 70000 m

Rate of fencing = ₹5 /m

Total cost of fencing 3 times = 3×5×70000

=₹1050000 Ans...

Answer 2

The perimeter of the land would be 1,100 m and the total cost of fencing would be ₹16,500.

Explanation:

Given that,

Length of the land = 350 m

Breadth of the land  = 200 m

The perimeter of the land = $2$ × $(l + b)$

Perimeter $=$  $2$ × $(350 + 200)$

$= 1100m$  

Rate of fencing = = ₹ $5$/m

Total cost of the fencing 3 times = $3$ × $5$ × $1100$

= ₹ 16,500

Thus, the perimeter of the land would be 1,100 m and the total cost of fencing would be ₹16,500.
