The perimeter of a rectangle is 26cm. It's width is 5cm. What is the length?
To find the length 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 perimeter is 26 cm and the width is 5 cm, we can substitute these values into the formula:
26 = 2(length + 5)
To find the length, we need to isolate it on one side of the equation. Let's simplify the equation:
26 = 2(length + 5)
26 = 2length + 10
Next, we can subtract 10 from both sides of the equation:
26 - 10 = 2length
16 = 2length
Finally, we can divide both sides of the equation by 2 to solve for the length:
16 / 2 = length
8 = length
Therefore, the length of the rectangle is 8 cm.
2(5) + 2x = 26
26 - 10 = 2x
