The answer if you are looking for it this way.2.23
The perimeter of a rectangle is twice the sum of its side lengths.
P=2(L+W), we are told that L=3W and P=176 so
2(3W+W)=176
2(4W)=176
8W=176
W=22 ft, since L=3W
L=66 ft
So the yard is 22 feet wide and 66 feet long.
Okay , wheres the questions at tho...?
The line is positive
The line is positive because it slants to the right.
