To find the area of a quadrilateral, multiply the length and width of the figure. The product will give you the area of the figure.
Baigan
well change it into another quadrilateral and then take away the area of the lines you added
The formula for the area of a quadrilateral is... BASE*HEIGHT/3
4 times 4
You cannot. The length of the sides of a quadrilateral do not provide sufficient information to find its area. In the same way the a square can be distorted into a thinner and thinner rhombus with a smaller and smaller area, so can any quadrilateral.
The only way to find the area is to have two sides to multiply them together unless you have the hypotenuse.
The area of the quadrilateral.
Firstly, all quadrilaterals are four sided. That is a the definition of a quadrilateral - a four sided figure. One way is to find the area of each half (i.e. two triangles) and add them together. The area of a triangle is half the length of the base times the height.
A quadrilateral does not have a surface area because it is not a voluminous figure.
A quadrilateral has 4 sides but may not be symmetric. Bretschneider's formula provided a method using side lengths and two opposite angles. Any scalene quadrilateral can be divided into four triangles and the area is the sum of their areas. (see the related link below)
