Answer:
Length = 8 ft.
Step-by-step explanation:
The perimeter of a rectangle can be represented by the formula P = 2w + 2l, where w is the width and l is the length.
Given what we're told, we can represent the length for this problem using the equation l = w + 3
Thus, to find the length, we plug in everything we know:
26 = 2(w +3) + 2w
26 = 2w + 6 + 2w
26 = 4w + 6
20 = 4w
5 = w
l = 5 + 3 = 8
