Answer:
The ratio of perimeter of ABCD to perimeter of WXYZ = 
Step-by-step explanation:
First, we have to determine the multiplicative factor of the dimensions for both figures.
Considering sides AB and WX,
multiplicative factor = 
= 1.5
So that:
XY = 6 x 1.5 = 9
YZ = 7 x 1.5 = 10.5
ZW = 7 x 1.5 = 10.5
Perimeter of ABCD = 6 + 7 + 7 + 8
= 28
Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12
= 42
The ratio of the perimeters of the two quadrilaterals can be determined as;
ratio = 
= 
= 
The ratio of the perimeter of ABCD to perimeter of WXYZ is
.
3(x-1)=2x+5
3x-3=2x+5
3x-2x=3+5
x=8

I hope it will help you.......
She walks 6/5 of a mile in 1 hour
So, she walks 1.2 miles per hour
15h + 80 = 140
If you wanted to solve how many hours he worked:
15h + 80 = 140
15h = 60
h = 4.
