Answer:
To evaluate the area of a quadrilateral, we divide it into two basic geometric figures, such as triangles. Then we find the area of the two individual triangles using the formula and add these areas to find the area of the quadrilateral.
Quadrilateral formulas Rectangle Parallelogram
Area l × b l × h
Perimeter 2 × (l + b) 2 × (l + b)
Quadrilaterals are composed of two triangles. Seeing as we know the sum of the interior angles of a triangle is 180°, it follows that the sum of the interior angles of a quadrilateral is 360°.
Since the quadrilateral graph is on the coordinate plane, you can use the distance formula to find the length of each side. For instance, if the quadrilateral is formed by points A, B, C, and D, you would find the length of AB, BC, CD, and DA by using distance = sqrt((X2-X1)^2 + (Y2-Y1)^2)
