Formula & Methodology
The width of a rectangle is calculated by subtracting the length of the two shorter sides (heights) from the length. The formula is:
Width = Length – (2 × Height)
Real-World Examples
Example 1
A room has a length of 12 feet and a height of 8 feet. What is the width?
Width = 12 – (2 × 8) = 4 feet

Interactive FAQ
What if the length is less than twice the height?
In that case, the width would be negative, which isn’t possible for a rectangle. You might need to recheck your measurements.
