5.7 is the answer because if one side is 7.9 the parallel is the same a rectangle. The is you add those, you get 15.8. The equation now is 15.8+x=27.2. 27.2-15.8 is 11.4 which is then divided to find the two sides which makes them 5.7.

Answer:

The length is 5.7 feet.

Step-by-step explanation:

A rectangle has a width of 7.9 feet and a perimeter of 27.2 feet.

Let the length be = x

Perimeter is given by :

[tex]P=2(L+W)[/tex]

We get;

[tex]27.2=2(x+7.9)[/tex]

=> [tex]27.2=2x+15.8[/tex]

=> [tex]2x=11.4[/tex]

Dividing both sides by 2 to get x;

x = 5.7 feet

Hence, length is 5.7 feet.
