A(-4,0) and (-1,4) are two given points.C and d are points which are symmetric to the given points A and B respectively with respect to Y-axis.Calculate the perimeter of Trapezium ABDC.
did you plot the points? Clearly the other two points are
C:(4,0) and D:(1,4)
So, the trapezium has bases 2 and 8, and height 4.
Think you can take it from there?
