04
How It Works
Rectangle and square dimensions are related through area, perimeter, and the Pythagorean theorem.
P = 2(L + W)
Rectangle Perimeter
Perimeter is the total distance around the rectangle.
d = √(L² + W²)
Rectangle Diagonal
The diagonal follows directly from the Pythagorean theorem.
A = s²
Square Area
All four sides of a square are equal.
P = 4s
Square Perimeter
Square perimeter equals four times the side length.
d = s√2
Square Diagonal
A square diagonal forms a 45-45-90 right triangle.
