The maximum width of a rectangle with a perimeter no greater than 100 centimeters and a length of 30 centimeters is blank centimeters

To find the maximum width of the rectangle, we can use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2 * (length + width)

Given that the length is 30 centimeters and the perimeter is no greater than 100 centimeters, we can substitute these values into the formula and solve for the width:

100 = 2 * (30 + width)

Dividing both sides of the equation by 2 gives:

50 = 30 + width

Subtracting 30 from both sides of the equation gives:

20 = width

Therefore, the maximum width of the rectangle is 20 centimeters.
