Answer:
22
Step-by-step explanation:
Given the following
GE = 3x - 11 FD = 2x
Let us assume GE is parallel to FD, hence GE = FD
3x - 11 = 2x
3x - 2x = 0+11
x = 11
Get GE
GE = 3x - 11
GE = 3(11)-11
GE= 33 - 11
GE = 22
Hence the length of GE is 22
The length l is given as:
l = 2 w – 6
where w is the width
We know that the fencing is 30 feet therefore the
perimeter (excluding the side of the house) is:
P = l + 2 w = 30
2 w – 6 + 2 w = 30
4 w – 6 = 30
w = 9
So the length l is:
l = 2 (9) – 6
l = 12
