The length of a rectangular dog run is 2 feet more than twice the width, w, and the perimeter of the dog run is 32 feet. Solve t
Natalija [7]

Answer:

The width is:

  • width = 4.7 feet

The length is:

  • length = 11.3 feet

Step-by-step explanation:

Given the equation

2w\:+\:2\left(2w\:+\:2\right)\:=\:32

2w+4w+4=32          ∵ a\left(b+c\right)=ab+ac

Add similar elements: 2w+4w=6w

6w+4=32

subtract 4 from both sides

6w+4-4=32-4

6w=28

Divide both sides by 6

\frac{6w}{6}=\frac{28}{6}

w=\frac{14}{3}

Hence, the width is:

w=\frac{14}{3}

w = 4.7 feet

Therefore, the width is: 4.7 feet

As the length is:

2w+2 = 2(14/3)+2

          = 28/3 + 2

           = 34/3

            = 11.3 feet

Therefore, the length is: 11.3 feet

SUMMARY:

The width is:

  • width = 4.7 feet

The length is:

  • length = 11.3 feet
