Calculate the width of a rectangle given its area and length. Simply enter the area and length, and our calculator will instantly compute the width using the formula W = A / L. Perfect for geometry problems, construction projects, and everyday measurements.
A rectangular garden bed has an area of 24 square feet and a length of 6 feet. What is its width?
Solution: W = A / L = 24 / 6 = 4 feet
A rectangular room has a floor area of 200 square feet and a length of 16 feet. Find the width.
Solution: W = A / L = 200 / 16 = 12.5 feet
A rectangular swimming pool covers an area of 500 square meters and has a length of 25 meters. Calculate its width.
Solution: W = A / L = 500 / 25 = 20 meters
A rectangular picture has an area of 96 square inches and a length of 12 inches. Determine the width.
Solution: W = A / L = 96 / 12 = 8 inches
The width of a rectangle is found by dividing its area by its length. This is derived from the basic area formula for a rectangle:
Rearranging to solve for width gives us W = A / L.
Where:
Input the total area of the rectangle. You can choose from square units, square meters, square feet, square inches, or square centimeters.
Input the length of the rectangle. Make sure to select the matching unit (units, m, ft, in, or cm) that corresponds to your area unit.
Click the "Calculate Width" button. The calculator will instantly compute the width using the formula W = A / L and show the step-by-step solution.
The results include a verification check (A = L × W) to confirm the calculation is correct. Use the examples tab for reference.
The width of a rectangle is the measure of its shorter side (or the side perpendicular to the length). In a rectangle, opposite sides are equal, so the width is the distance between the two shorter parallel sides. Together with the length (the longer side), the width defines the shape and size of the rectangle.
The area of a rectangle is calculated by multiplying its length by its width (A = L × W). This fundamental relationship means that if you know any two of these three values, you can calculate the third. When you need to find the width, simply rearrange the formula: W = A / L. This makes it easy to determine the missing dimension of any rectangular space.
