MATH CALCULATOR
Generic Rectangle Calculator
Easily calculate the area, perimeter, and diagonal of rectangles with our online tool.
What is the Generic Rectangle Calculator & How does it work?
A rectangle is a four-sided polygon with all right angles. The area of a rectangle can be calculated by multiplying its length by its width.
The perimeter of a rectangle is the total distance around the outside, which can be found by adding together twice the length and twice the width.
The diagonal of a rectangle can be calculated using the Pythagorean theorem:.
The perimeter of a rectangle is the total distance around the outside, which can be found by adding together twice the length and twice the width.
The diagonal of a rectangle can be calculated using the Pythagorean theorem:
d = sqrt{l^2 + w^2}
d = diagonal, l = length, w = width

Frequently Asked Questions
How do I calculate the area of a rectangle?
Multiply the length by the width to find the area.
What is the formula for the perimeter of a rectangle?
Add together twice the length and twice the width: 2(length + width).
How do I find the diagonal of a rectangle?
Use the Pythagorean theorem: d = sqrt(l^2 + w^2), where l is length and w is width.
Can this calculator handle decimal measurements?
Yes, you can enter decimal values for length and width to get precise results.
Is there a limit to the size of the rectangle I can calculate?
No, our calculator supports a wide range of sizes, from small to large dimensions.
What if I only know two measurements, like length and diagonal?
You can still find the width using the Pythagorean theorem: w = sqrt(d^2 - l^2).
Can this calculator be used for squares as well?
Yes, since a square is a special type of rectangle with equal sides, you can use either length or width for both dimensions.
