perpendiculars from the vertices are given, then the area of the quadrilateral is calculated as: Areaof quadrilateral = (½) × diagonal length × sum of thelength of the perpendiculars drawn from the remaining two vertices.
In geometry, a quadrilateral can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners. We can find the shape of quadrilaterals in various things around us, like in a chess board, a deck of cards, a kite, a tub of popcorn, a sign board and in an arrow.
What is the formula for finding area of quadrilateral?
If the diagonal and the length of the perpendiculars from the vertices are given, then the area of the quadrilateral is calculated as: Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.
Different types of quadrilaterals?
There are 5 types of quadrilaterals on the basis of their shape. These 5 quadrilaterals are:
Rectangle
Square
Parallelogram
Rhombus
Trapezium
Rectangle
A rectangle is a quadrilateral with four right angles. Thus, all the angles in a rectangle are equal (360°/4 = 90°). Moreover, the opposite sides of a rectangle are parallel and equal, and diagonals bisect each other.
Properties of rectangles
A rectangle has three properties:
All the angles of a rectangle are 90°
Opposite sides of a rectangle are equal and Parallel
Diagonals of a rectangle bisect each other
Rectangle formula – Area and perimeter of a rectangle
If the length of the rectangle is L and breadth is B then,

Rectangle formula – Area and perimeter of a rectangle
If the length of the rectangle is L and breadth is B then,
Area of a rectangle = Length × Breadth or L × B
Perimeter of rectangle = 2 × (L + B)
