Perimeter of rectangle = 2 (length + breadth) = 2 (15 + 11) cm = 52 cm What is the area and perimeter of a rectangle where the length and breadth are 15 cm and 11 cm respectively?Īrea of rectangle = (length × breadth) cm 2 = (15 X 11) cm 2 = 165 cm 2 Here is an example, for better understanding of the definition of a rectangle – There is congruency in opposite angles which are created when two diagonals bisect.ĭiagonals of a rectangle bisect each other, i.e., both are divided equally and congruent as well.Ī rectangle is held to be a special instance of parallelogram comprising of right angles. Opposite sides of a rectangle are congruent as well as parallel. Proceeding from the rectangle definition, its main properties are – The formula reflects that as the opposite sides of a rectangle are parallel, the rectangle’s perimeter would be two times the sum of length and breadth. It is the product of adjacent sides of a rectangle, that is, the product of its length and breadth. To define the area of a rectangle, its length and breadth are taken into consideration. Also, even though all parallelograms may not be rectangles but all rectangles are necessarily parallelograms. Furthermore, it can also be an equiangular quadrilateral, given that all of its angles are equal.Īll squares are rectangles, but not all rectangles are squares. Owing to the existence of parallel sides in a rectangle, it is termed as a parallelogram. From rectangle definition, these characteristics are evident in the figure indicated below. Moreover, sides facing each other are of the same lengths as well as parallel that is, the distance between those two sides always remain the same at any given point. It means that two sides always meet at right angles in a rectangle. In geometry, rectangle comprises of a 2D shape having four vertices and four sides and each angle measures 90°. Read on to know more about the definition of Rectangle and its other dimensions. The present terminology is derived from the Latin word ‘rectangulus’ which can be divided into the components of ‘angulus’ which means angle and ‘rectus’ which means right. Previously, it was also known as an equiangular quadrilateral. ![]() ![]() In plane geometry, the rectangle was held to be simply a quadrilateral having 4 right angles. A rectangle in Euclidian geometry was put forward around 300 B.C. ![]()
