The length of the fencing is 62.4 feet.
The width of the fencing is 17.6 feet.
Given,
The measurement of the Christmas garland = 160 feet
The width of the fencing = w
The length of the fencing, l = 4w - 8
We have to find the length and width of the fencing.
Here,
Perimeter can be taken as 160. Because garland will cover the entire fencing.
Perimeter = 2(l + w)
160 = 2(4w - 8 + w)
160 = 2(5w - 8)
160/2 = 5w - 8
80 + 8 = 5w
88/5 = w
width = 17.6 feet
Now,
l = 4w - 8
l = 4 × 17.6 - 8
l = 70.4 - 8
length = 62.4 feet
That is,
The length of the fencing is 62.4 feet.
The width of the fencing is 17.6 feet.

Answer:
0.1*√20000 = 14.1421356237
-0.05*√28800 = -8.48528137424
Step-by-step explanation:
Additive property of equality states that:
if a=b, then a+c = b+c,
that is, if 2 quantities of the same value are added the same quantity, they are again equal.
In our problem a=AD, b=DB, and c= CD=DE
thus a+c=b+c means <span>AD + CD = DE + DE,
by the </span><span>Addition Property
