the perimeter of a rectangular sheet is 125cm , breath is 21.4cm what is its length?
2L * 2W = 125 cm.
2L + 2*21.4 = 125
2L + 42.8 = 125
2L = 125-42.8 = 82.2
L = 41.1 cm.
To find the length of the rectangular sheet, we can use the formula for the perimeter of a rectangle:
Perimeter = 2 * (Length + Breadth)
Given that the perimeter is 125 cm and the breadth is 21.4 cm, we can substitute these values into the formula:
125 cm = 2 * (Length + 21.4 cm)
Dividing both sides of the equation by 2 gives:
62.5 cm = Length + 21.4 cm
To isolate the length, we subtract 21.4 cm from both sides of the equation:
Length = 62.5 cm - 21.4 cm
Simplifying, we get:
Length = 41.1 cm
Therefore, the length of the rectangular sheet is 41.1 cm.
To find the length of the rectangular sheet, we can use the formula for the perimeter of a rectangle, which is:
Perimeter = 2(length + width)
Given that the perimeter is 125 cm and the width (breath) is 21.4 cm, we can substitute these values into the equation and solve for the length:
125 = 2(length + 21.4)
First, let's simplify the equation by distributing the 2:
125 = 2length + 2(21.4)
125 = 2length + 42.8
Now, let's isolate the variable (length) by subtracting 42.8 from both sides of the equation:
125 - 42.8 = 2length
82.2 = 2length
Finally, divide both sides of the equation by 2 to solve for the length:
82.2 / 2 = length
Length = 41.1 cm
Therefore, the length of the rectangular sheet is 41.1 cm.
