The diagonal AC cut the rectangle into two congruent right – angled triangles which are triangle ABC and triangle ADC. Therefore, the area of the rectangle will be equal to twice the area of the right-angled triangle. The diagonals of the rectangle divide the rectangle into two equal right-angled triangles. Step 2: Multiply the values of length and breadth Step 1: Write the given dimensions of length and breadth The area of any rectangle can be calculated if its length and breadth are known.īelow are the steps to find the area of a rectangle

The formula for the area of rectangle is equal to the product of its length and breadth. Let us take a rectangle ABCD which has four sides i.e., AB, BC, CD and DA NOTE : Squares of unit length mean that the length of each side of the square is one. The area of a rectangle can also be defined as the number of square units or squares of unit length that can fit inside the rectangle. The Sum of all four angles is 360 degrees.Īrea of a rectangle is the space occupied by a rectangle within four sides or boundaries of a rectangle.Each angle of the rectangle is 90 degrees.The diagonal of the rectangle divides it into two congruent triangles.

Opposite sides of a rectangle are parallel to each other.

Two adjacent sides are never equal in the case of rectangle.

Opposite sides of the rectangle are equal.

All angles of a rectangle are 90 degrees or all the angles of the rectangle are right angles.Įxamples of rectangles are: mobile phones, laptop screen, doors, walls, notebooks, etc. The space occupied within the boundary of a closed figure is called its area.Īrea can also be defined as the number of square units that can fit inside the polygon.Ī rectangle is a two-dimensional polygon with four sides and four angles with opposite sides are equal and parallel to each other.
