use this formula
Step-by-step explanation:
Area of a quadrilateral
A quadrilateral is a figure, or shape, with four sides. Rectangles and squares are both quadrilaterals.
The formula of area of rectangles and squares are rather straightforward--it is width times length. However, for squares, the width equals the length.
A
=
width
×
length
In fact, you can cut up any quadrilateral and rearrange the pieces to make a rectangle. Since you are using the pieces from the old quadrilateral, the new rectangle will has the same area. This way, the area formula of a rectangle applies to all quadrilaterals!
