Answer:

[tex]\huge\boxed{1 \frac{4}{5}\ \text{ft}}[/tex]

Explanation:

Change [tex]\frac{1}{5}[/tex] so that is has a common denominator.  [tex]\frac{1*2}{5*2}=\frac{2}{10}[/tex]

Make an equation.  [tex]\frac{7+7+2+2}{10}[/tex]

Add.  [tex]\frac{14+4}{10}[/tex]

Add.  [tex]\frac{18}{10}[/tex]

Divide both sides by 2.  [tex]\frac{9}{5}[/tex]

Convert to a mixed number.  [tex]1 \frac{4}{5}[/tex]

Answer:

1 4/5 ft.

Step-by-step explanation:

Change 7/10 into 70

Change 1/5 into 20

( It will be easier to find perimeter this way )

Formula: P=2(l+w)

P=2(l+w)=2·(70+20)=180

Then, you change the 180 back into a fraction to get 1 4/5.
