To find the width of a rectangle, we can use the formula for perimeter:
Perimeter = 2(length + width)
We are given that the perimeter is 86 cm and the length is 36 cm.
So, we can substitute these values into the formula:
86 = 2(36 + width)
Now, let's solve for the width:
86 = 72 + 2(width)
86 - 72 = 2(width)
14 = 2(width)
Divide both sides by 2:
7 = width
Therefore, the width of the rectangle is 7 cm.
