Let width = w
Let length = w + 3 [It's three feet more than the width.]
Perimeter = 2(length) + 2(width)
26 = 2(w + 3) + 2(w)
26 = (2w + 6) + (2w)
26 = 4w + 6
20 = 4w
w = 5 feet
Checking, width = 5 feet, length = (5+3=) 8 feet
P = 2(5) + 2(8)
P = 10 + 16
P = 26.
The length is 8 feet and the width is 5 feet.

Let width = w
Length = w +3
26 = 2 ( w + w + 3)
26 = 2w + 2w + 6
26 = 4w + 6
20 = 4w
5 = w
Therefore width is 5 and length is 8.

L= 3+w
2L+2w=26
6+4w=26
w=5
L=8

x= Lenght Y= Width
x=Y+3, x+y=13, (y+3)=y=10, 2y+3+10, y=5 x=5+3, x+8
8,5

length = width+3
so if width is X, length is x+3
perimeter= x+3 +x+3+x+x=26
4X+6=26
4X= 20
X= 5
WIDTH =5, LENGTH=8

8ft X 5ft. the long sides are 3 ft longer, so thats 6 feet total. remove that and you would have a 5X5 square, so add the 3 feet to the long sides, and you get 8 ft.
