The length of a rectangle is twice that of the width. The perimeter of the rectangle is 24 cm. What is the width of the rectangle?
The width of the rectangle is _________ cm
width --- x
length --- 2x
2x + 2(2x) = 24
solve for x
To find the width of the rectangle, we need to use the given information about its length and perimeter. Let's go step by step.
Let's assume the width of the rectangle is "x" cm.
According to the statement, the length of the rectangle is twice that of the width, meaning the length is 2x cm.
The formula to find the perimeter of a rectangle is: P = 2(l + w), where P represents the perimeter, l represents the length, and w represents the width.
Given that the perimeter is 24 cm, we can substitute the values into the formula:
24 = 2(2x + x)
Now we can simplify the equation:
24 = 2(3x)
24 = 6x
To find the value of x, we divide both sides of the equation by 6:
x = 24/6
x = 4
Therefore, the width of the rectangle is 4 cm.
