What is Rectangle?

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral.

Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram.

What is the Rectangle Formulas?

Area of a rectangle: A = ab Perimeter of a rectangle: P = 2a + 2b Polygon diagonals of a rectangle: p = q = √(a2 + b2)

Calculate A, P, b | Given p, a

Given diagonals and side length a calculate area, perimeter and side b

b = √(p² - a²)

A = ab

P = 2a + 2b

Calculate A, P, a | Given p, b

Given diagonals and side length b calculate area, perimeter and side a

a = √(p² - b²)

A = ab

P = 2a + 2b

Calculate A, p, b | Given P, a

Given perimeter and side length a calculate area, diagonals and side b

b = (P - 2a) / 2

A = ab

p = q = √(a² + b²)

Calculate A, p, a | Given P, b

Given perimeter and side length b calculate area, diagonals and side a

a = (P - 2b) / 2

A = ab

p = q = √(a² + b²)
