Question

The length of a rectangle is 3 meters less than twice its width. How do you write an equation to find the length of the rectangle?

Answer 1

`l = 2w - 3`

Explanation:

1) Let `w` represent the width of the rectangle.

2) "Twice its width" is the same as multiplying by `2` which would give `2w`

3) "3 meters less than" means to subtract `3` or "- 3".

4) combining these would give the equation for the length, lets call it `l`, as:

`l = 2w - 3`
