How do you find the area of a quadrilateral with 4 sides?
In other words, for any quadrilateral:
- Area = 0.5 Side 1 × Side 4 × sin(Side 1&4 angle) + 0.5 × Side 2 × Side 3 × sin (Side 2&3 angle) or.
- Area = 0.5 a × d × sin A + 0.5 × b × c × sin C.
- Example: You already have the sides and angles you need, so let’s solve:
What are 5 examples of quadrilaterals?
They include trapezium, parallelogram, rhombus, rectangle, square, kite, etc. Concave quadrilaterals: These are the quadrilaterals with at least one interior angle greater than 180 degrees, and at least one of the two diagonals is outside the quadrilaterals.
How do you find the area of a quadrilateral triangle?
Hence, the formula to find the area of the quadrilateral is derived as: Area of General Quadrilateral Formula = 1/2 x diagonals length x ( sum of the height of two triangles ).
