What is the area of a 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.
What is the perimeter of the quadrilateral?
The perimeter of a quadrilateral is the total length of its boundary. For example, the perimeter of a quadrilateral ABCD can be expressed as, Perimeter = AB + BC + CD + DA. This means if all the sides of a quadrilateral are known, we can get its perimeter by adding all its sides.
What is the formula for area and perimeter?

| Figures | Area Formula | Variables |
|---|---|---|
| Area of Rectangle | Area = l × w | l = length w = width |
| Area of Square | Area = a2 | a = sides of the square |
| Area of a Triangle | Area = 1/2 b×h | b = base h = height |
| Area of a Circle | Area = πr2 | r = radius of the circle |

How do you find perimeter formula?
The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle.
What is the area of quadrilateral ABCD in which AB 3cm BC 4cm CD 4cm da 5cm and AC 5cm?
We have found that area of a quadrilateral ABCD in which AB = 3 cm, BC = 4 cm, CD = 4 cm, DA = 5 cm and AC = 5 cm is 15.2 cm2.
How do you calculate the perimeter of a quadrilateral?
Perimeter of Quadrilateral. The formula to find the perimeter of the quadrilateral = sum of the length of all the four sides. Here the lengths of all the four sides are 5 cm, 7 cm, 9 cm and 11 cm.
What are the 6 types of quadrilaterals?
There are primarily six different types of quadrilaterals used in geometry. These are parallelogram, rectangle, square, rhombus, kite and trapezoid.
What are the similarities between area and perimeter?
The significant differences between area and perimeter are provided in detail, in the following points: The area is described as the measurement of the surface of the object. Perimeter refers to the outline that surrounds a closed figure. .Area represents the space occupied by the object.
What is the area of an irregular quadrilateral?
The Area of any Irregular Quadrilateral. In a quadrilateral the diagonal is 42 cm and the two perpendiculars on it from the other vertices are 8 cm and 9 cm respectively. Find the area of the quadrilateral.
