the width of a rectangle is w cm . if its length is 5cm longer than its width. Writedown an expression for the perimiter of the rectangle
The length of the rectangle is 5 cm longer than the width, so the length can be expressed as w + 5 cm.
The perimeter of a rectangle is given by the equation P = 2(length + width).
Substituting the given values, we have:
P = 2(w + (w + 5))
Simplifying the expression further:
P = 2(2w + 5)
P = 4w + 10
Therefore, the expression for the perimeter of the rectangle is 4w + 10.
The perimeter of a rectangle is the sum of all its sides.
The given width of the rectangle is w cm.
The length of the rectangle is 5 cm longer than its width, which means the length is (w + 5) cm.
The perimeter of the rectangle can be expressed as:
2(w) + 2(w + 5)
Simplifying the expression, we get:
2w + 2w + 10
Combining like terms, the expression for the perimeter of the rectangle is:
4w + 10 cm
To write down an expression for the perimeter of the rectangle, we need to consider the formula for calculating the perimeter of a rectangle, which is given by the sum of all the sides.
Let's analyze the rectangle:
The width is given as "w cm."
The length is stated as "5 cm longer than its width." So, the length is w + 5 cm.
The formula for the perimeter of a rectangle is P = 2 * (length + width). Plugging in the values, we get:
P = 2 * (w + (w + 5))
Now, we can simplify the expression:
P = 2 * (2w + 5)
P = 4w + 10
Therefore, the expression for the perimeter of the rectangle is 4w + 10.
