Question

The length of a rectangular plot of land is 50 m and its width is 30 m, A triple fence has to be put along its edges. If the wire costs 60 rupees per
metre, what will be the total cost of the wire needed for the fence?​

​

Answer 1

Answer:

Total Cost of 480 m wire that is required for the fencing will be 28800 rupees.

Step-by-step explanation:

Given-:

Lenght of the rectangular plot (l) = 50 m

Breath of the rectangular plot (b) = 30 m

Logic-:

For fencing we need to take out the perimeter of the rectangular plot i.e 2(l+b).

So perimeter of rectangular plot = 2(l+b)

=> 2(50+30)

=> 2*80

=> 160 m

According to the question it is is fenced three times then, Total perimeter will be

=> 3*16m

=> 480 m

Now;

Given cost of 1 m wire = 60 rupees.

Then cost of 480 m will be

=> 480*60

=> 28800 rupees

Therefore-:

Total Cost of 480 m wire that is required for the fencing is 28800 rupees.

Answer 2

Length of wire required = 3(Perimeter) = 3*2(l+b) = 2(80) = 480 m

Cost = 480*60 = rs 28800
