Formula
Area of Rectangle = b*h
Perimeter of Rectangle = 2(b) + 2(h)
Perimeter of Rectangle = 2(b) + 2(h)
where,
b = base, h = heigth
Area of Parallelogram = b×h
Perimeter of Parallelogram = 2(b) + 2(h)
where,
b = breadth, h = height
A rectangle is defined as a quadrilateral where all four of its angles are right angles.
The opposite sides are parallel and congruent.
The diagonals bisect each other.
The diagonals are congruent.
A rectangle is also a parallelogram.
Examples:
Find the area and perimeter of a rectangle for the breadth 4 and the height 5.
Step 1: Find the area.
Area = b×h = 4×5 = 20
Step 2: Find the perimeter.
Perimeter = 2(b) + 2(h) = 2(4) + 2(5) = 8 + 10 = 18.
