Mr. Timmons wanted to fence in his rectangular back yard so that his son could play soccer. He bought 180 feet of fencing, which
elixir [45]

Answer:

The length of the yard is 60 feet while the width is 30 feet.

Step-by-step explanation:

If the length of Mr. Timmon's backyard is double the width, then the dimensions are related by the following expression:

length = 2*width

We also know the perimetter, since he has the exact length of fence to surround his whole yard, which is 180 feet. The perimeter of a rectangle is given by:

perimeter = 2*length + 2*width

Therefore,

180 = 2*length + 2*width

With the length being double the width, we have:

180 = 2*(2*width) + 2*width

180 = 4*width + 2*width

6*width = 180

width = 180/6 = 30

length = 2*width = 2*30 = 60

The length of the yard is 60 feet while the width is 30 feet.

KatRina [158]
To solve this, you will need to divide the payment by 4 if she is doing four of the same payments.

196 / 4 = 49

so she will pay $49 a month.
