Answer:
length = 11 ft, width = 6 ft
Step-by-step explanation:
Let w be the width, l be the length and p the perimeter. You can write down the following equations:
1. w = l - 5
2. p = 2*(w + l)
Now you have two equations with two unknown.
Plugging eq.1 in eq.2:
p = 2*(l-5 + l)
p = 2*(2*l - 5)
p = 4*l - 10
Remember p = 34
34 = 4*l - 10
4*l = 44
l = 11
Using eq.1 to solve for w:
w = 11 - 5
w = 6
