Question

Find the cost of fencing a rectangular field of dimensions 16m by 12m at Rs.40 per meter.

Answer 1

Answer:

The cost of fencing a rectangular field of dimensions 16m by 12m at Rs.40 per meter is Rs 7680.

Step-by-step explanation:

If length = 16 m

Then breadth of rectangular filed = 12 m

First, find the area of the rectangular field and then find the cost of fencing.

The area of the rectangular field = Length × breadth

= 16 × 12

= 192 sq. m

Now the cost of fencing a rectangular field  at Rs.40 per meter = 40 ×  192

= 7680 Rs

Answer 2

Answer:

The cost of fencing the rectangular field=2240 Rs

Step-by-step explanation:

The length of the rectangular field= 16 m

And the breadth of the rectangular field is = 12m

Now we have to find the cost of fencing the rectangular field at Rs. 40 per meter

So we have to find the perimeter of the rectangular field first

Now, the perimeter of the rectangular field = 2×(length+breadth) = 2×( 16+12) = 2× 28m= 56 m

Now the cost of fencing 56m perimeter of the rectangular field at Rs. 40 per meter = 56×40 Rs. = 2240 Rs.
