What is the formula for area of a quadrilateral?

What is the formula for area of a quadrilateral?

Area = base × height, or A = b × h for short. Example: If the base of a rectangle has a length of 10 inches and the height has a length of 5 inches, then the area of the rectangle is simply 10 × 5 (b × h) = 50 square inches.

How do you find the area of a irregular quadrilateral?

The area of any irregular quadrilateral can be calculated by dividing it into triangles. Example: Find the area of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.

What is the formula of area of quadrilateral ABCD?

Length of the diagonal (BD)=11cm. ∴ Area of quadrilateral =21d(h1+h2)=21×12×11=6×11=66 cm2.

How do you find the area of a quadrilateral with 4 points?

How do we calculate the area of this quadrilateral using the coordinates of the four vertices? The answer is simple. We divide the quadrilateral in two triangles (using either of the diagonals), calculate the (positive value of) the areas of each triangle, and add these values to obtain the total area.
