What is the breadth of a rectangular sheet of perimeter100cmand length...
The perimeter of a rectangular sheet = 100 cm
Length of the rectangular sheet (l) = 35 cm
Let the breadth be 'b' cm
Perimeter of a rectangular sheet = 2 (Length + Breadth)
100 = 2l + 2b
100 = 2 × 35 + 2b
100 = 70 + 2b
2b =100 - 70
b = 30/2
b = 15 cm

What is the breadth of a rectangular sheet of perimeter100cmand length...
To find the breadth of a rectangular sheet, we need to use the formula:
Perimeter = 2(length + breadth)
Given that the length of the rectangular sheet is 35cm and the perimeter is 100cm, we can substitute these values into the formula and solve for the breadth.
Substituting the given values:
100cm = 2(35cm + breadth)
Expanding the equation:
100cm = 70cm + 2breadth
Rearranging the equation:
2breadth = 100cm - 70cm
2breadth = 30cm
Dividing both sides of the equation by 2:
breadth = 30cm ÷ 2
breadth = 15cm
Therefore, the breadth of the rectangular sheet is 15cm.
The correct answer is option C.
Perimeter = 2(length + breadth)

Substituting the given values:
100cm = 2(35cm + breadth)
Expanding the equation:
100cm = 70cm + 2breadth

2breadth = 30cm
Dividing both sides of the equation by 2:
breadth = 30cm ÷ 2
breadth = 15cm
Therefore, the breadth of the rectangular sheet is 15cm.
The correct answer is option C.
