A rectangle has perimeter 88cm and length 35cm. What is its width?
The width is enter your____ cm.
The width is enter your 9____ cm.
To find the width of a rectangle with a given length and perimeter, we can use the formula for the perimeter of a rectangle, which is given by P = 2(length + width).
Given that the length of the rectangle is 35 cm and the perimeter is 88 cm, we can substitute these values into the equation to solve for the width.
88 = 2(35 + width)
Now, let's solve for the width.
First, distribute the 2 to the terms inside the parentheses:
88 = 70 + 2(width)
Next, subtract 70 from both sides of the equation:
88 - 70 = 2(width)
18 = 2(width)
Finally, divide both sides of the equation by 2 to isolate the width:
18/2 = width
Thus, the width of the rectangle is 9 cm.
To find the width of the rectangle, we need to use the formula for the perimeter of a rectangle, which is given by P = 2(L + W), where P represents the perimeter, L represents the length, and W represents the width.
In this problem, we're given that the perimeter is 88cm and the length is 35cm. We can substitute these values into the formula and solve for the width.
88 = 2(35 + W)
Now, let's simplify the equation:
88 = 70 + 2W
Next, let's isolate the variable W:
88 - 70 = 2W
18 = 2W
Finally, we divide both sides of the equation by 2 to solve for W:
W = 18/2
W = 9
Therefore, the width of the rectangle is 9cm.
