Question

the vertices of a quadrilateral in the coordinate plane are known. how can the perimeter of the figure be found

Answer 1

If the vertices of the quadrilateral are know then just find the distance of the sides using distance formula that is √(x2-x1)^2+(y2-y1)^2

after the distances are known just add them to get the perimeter of the quadrilateral

perimeter is nothing but the distance of the boundary the figure
