The formula for the area of a quadrilateral?
The area of the general quadrilateral formula = 1/2 x the length of the diagonal x (the sum of the heights of the two triangles).
What is the formula for the area of quadrilateral ABCD?
As can be seen from the above figure, the area of the quadrilateral ABCD = the area of ΔBCD + the area of ΔABD. Therefore, the area of quadrilateral ABCD = (1/2) × d × h1 h 1 + (1/2) × d × h2 h 2 = (1/2) × d × (h1+h2 h 1 + h 2 ).
How do you find the area of a quadrilateral with 4 sides?
Example: In a quadrilateral, the diagonal is 42 centimeters, and the two perpendiculars to the other vertices are 8 centimeters and 9 centimeters. Find the area of the quadrilateral.area ABCD=12×9×42+12×8×42=189+168= 357 square meters.
How to calculate the area of a trapezoid?
To find the area of this trapezoid, follow a three-step strategy:
- Divide the quadrilateral into two triangles by constructing diagonals that do not interfere with the known interior angles.
- Use the formula to calculate the area of each triangle.
- Add the areas of the two triangles.
How to find area?
Find the area of the rectangle, multiply its height by its width. For a square, you just need to find the length of one of the sides (since every side is the same length) and multiply it by itself to find the area.

What is the area of ABCD?
The area of ABCD is Product of 6 and 8, equal to 48. The unit of measurement will be « square inches », as the lengths are multiplied, so are the units. Alternatively, the formula for calculating the area of a rectangle is derived by dividing the shape into two equal-sized right triangles.
What is the area of ΔABC?
Answer: The area of a triangle is the area between the sides of the triangle. Area of ΔABC = 1/2 × base × height. Let us know the basics of the area of a triangle.If ABC is an equilateral triangle, the area ΔABC = (√3/4)a2 where a is the length of one side of an equilateral triangle.
How to find the area of ABCD?

What is the formula for a rhombus?
The formula for a rhombus is defined for two parameters, the area and the perimeter: Area of rhombus = 1/2 × d1 d 1 × d2 d 2 where d1 d 1 and d2 d 2 are the diagonals of the rhombus.
What is the formula for an equilateral quadrilateral?
If we assume that the length of the square is L, then the length of the diagonal = L √2. Area of square = L2. A quadrilateral with four sides of equal length is a rhombus. It is sometimes called an equilateral quadrilateral because of its equal length.
What is the quadrant area?

How do you find the area of a quadrilateral with a vector?
Consider a quadrilateral whose sides are given by the vectors →a,→b,→c and →d such that →a+→b+→c+→d=0.I was told that the area of a quadrilateral can be passed through half of the matrix determinant whose columns are given by the diagonal of the quadrilateral.
What is considered a regular quadrilateral?
A regular quadrilateral must have 4 equal sides, 4 equal angles, and its diagonals must bisect each other. … so, a square is a regular quadrilateral. A rhombus is a quadrilateral with all sides equal, its diagonals bisect each other, but none of its angles are equal.
What is an uneven quadrilateral?
A quadrilateral is a polygon with four sides (hence the beginning of « quad », which means « four »).Polygons with unequal sides are called irregular polygons, so the graph you describe is trapezoid.
What has 4 equal sides but no right angles?
So we can conclude that a quadrilateral with four equal sides and no right angles can be called as diamond.
