Answer:
The ratio is .
Step-by-step explanation:
The ratio of the perimeters of Quad ABCD to Quad WXYZ =
But considering sides AB and WX,
representative factor for both figures =
So that;
WX = 12
XY = 1.5 x 6 = 9
YZ = 1.5 x 7 = 10.5
WZ = 1.5 x 7 = 10.5
Thus,
perimeter of Quad ABCD = 6 + 7 + 7 + 8
= 28
perimeter of Quad WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of Quad ABCD to Quad WXYZ =
=
