Question

The perimeter of a rectangle is P = 2w + 21 where w the width of the rectangle is and I

s the length of the rectangle. What is this formula in terms of the width?

Answer 1

The formula for the perimeter of a rectangle in terms of the width is P = 2w + 21, where w is the width of the rectangle. By substituting the given width value into the formula, we can find the perimeter of the rectangle.

Step-by-step explanation:

The formula for the perimeter of a rectangle in terms of the width is P = 2w + 21, where w is the width of the rectangle. To find the perimeter of a rectangle, you can substitute the given width value into the formula and simplify. Let's take an example:

If the width of a rectangle is 100 feet, we can substitute w = 100 into the formula P = 2w + 21. P = 2(100) + 21 = 200 + 21 = 221 feet. So, the perimeter of the rectangle is 221 feet.
