.
P=2(L+W)
4X+72ft=2((3X+2)+X)
4X+72ft=2(4X+2)
4X+72=8X+4
68ft=4X
17ft=X
The width is 17ft
.
L=3X+2
L=3(17ft)+2
L=51ft+2=53ft
ANSWER: The length of the garden is 53 feet.
.
CHECK:
4X+72ft=2((3X+2)+X)
4(17ft)+72ft=2((3(17ft)+2ft)+17ft)
68ft+72ft=2(53ft+17ft)
140ft=2(70ft)
140ft=140ft
.

The perimeter is twice x + (3x+2)=2*(4x+2)
=8x+4
8x+4=4x+72
4x=68
x=17 feet

3x+2, the length, is 53 feet.
check
The perimeter is 70*2=140 feet=4(17)+72
