How can you use a formula for one measurement to write a formula for a different measurement?

Write the formula for one measurement, then solve the formula for the different measurement you want to find and use this new formula to find that measurement.

Step-by-step explanation:

 We can understand this through an example.

If we need to find the lenght of a rectangle whose width is 4 feet and whose perimeter is 28 feet, we can use a formula for one measurement to write a formula for a different measurement:

 - We need to write the formula for the perimeter of a rectangle:

Where "l" is the lenght and "w" is the width.

- Since we know the width and the perimeter of the rectangle and we need to find the lenght, we can solve for "l":

Now we get a new formula for calculate a differente measurement (the lenght of the rectangle).

- Substituting values, we get:

you would need to know all the numbers that are on there
