Calculate the perimeter of a rectangle whose length and breadth are 15m and 12m.find the cost of fencing the field at the rate of rs 25 per meter.
P=2L+2W
cost=rs 25*perimeter
To calculate the perimeter of a rectangle, you need to add the lengths of all its sides. For a rectangle, the opposite sides are equal in length, so you can add the lengths of the two adjacent sides and multiply by 2.
Given that the length of the rectangle is 15m and the breadth is 12m, the perimeter can be calculated as follows:
Perimeter = 2 × (Length + Breadth)
Perimeter = 2 × (15m + 12m)
Perimeter = 2 × 27m
Perimeter = 54m
Now, to find the cost of fencing the field at a rate of Rs 25 per meter, you need to multiply the perimeter by the cost per meter:
Cost of Fencing = Perimeter × Cost per meter
Cost of Fencing = 54m × Rs 25/m
Cost of Fencing = Rs 1,350
Therefore, the cost of fencing the field will be Rs 1,350.
