About This ArticleArticle SummaryX Before you can find the area of a regular quadrilateral, start by identifying the type of quadrilateral in the problem, since different types of quadrilaterals require different equations. For rectangles or rhombuses, simply multiply the base by the height to find the area. For squares, multiply one side by itself to get the area. If you have a parallelogram, multiply the diagonals and divide by 2 to get the area. To find the area of a trapezoid, add the base and the height together, and divide that number by 2 times the height. If you want to find the area of an irregular quadrilateral, keep reading the article! Did this summary help you? Thanks to all authors for creating a page that has been read 1,653,452 times.

Did this article help you?How do you find the area of a quadrilateral with 4 sides?If the sides of a quadrilateral (a, b, c, d) are given, and two of its opposite angles (θ1 and θ2) are given, then the area of quadrilateral can be calculated as follows: A r e a o f Q u a d r i a t e r a l = ( s − a ) ( s − b ) ( s − c ) ( s − d ) − a b c d c o s 2 θ 2 s q u a r e u n i t s .
How do you find the area of a shape with 4 different sides calculator?Use the following equation: Area = side × side or A = s. Example: If one side of a square has a length of 4 feet, (t = 4), then the area of this square is simply t2, or 4 x 4 = 16 square feet.. Squares: Four sides, all the same length. ... . Rectangles: Four sides; opposite sides have same lengths.. What is the equation for quadrilateral area?Intuition for why the area of a parallelogram is A = b h A=bh A=bh. The formula for the area of a parallelogram is base times height, just like the formula for the area of a rectangle.
