Question

write the formula to calculate area of quadrilateral when Co ordinates are given​ can you answer it please...

Answer 1

Area of Quadrilateral Using Coordinates

Subtract (2) from (1) and multiply the difference by 1/2 to get area of the quadrilateral ABCD.

Answer 2

If four coordinates are given then:-

• Find length of the sides using distance formula

`\boxed{\sf √((x_2-x_1)^2+(y_2-y_1)^2)}`

• Now break down into two triangles .
• Use herons formula and find areas of the triangles .add them and get the area
