Determine which type of quadrilateral ABCD is and find its perimeter if you know the coordinates of vertices: A/2,4 /, B / -2,1 /, C / -2, -2 /, D/2, -5 /.

Correct answer:

x = Lichobeznik/Trapezium
o =  22

Step-by-step explanation:

A=(2,4) B=(2,1) C=(2,2) D=(2,5) AB=(AxBx)2+(AyBy)2=(2(2))2+(41)2=5 BC=ByCy=1(2)=3 CD=(CxDx)2+(CyDy)2=((2)2)2+((2)(5))2=5 AD=AyDy=4(5)=9  o=AB+BC+CD+AD=5+3+5+9=22
