Kathy is fencing in her yard that has an area of 800 square feet. her yard is in the shape of a rectangle where the length is 60 less than 5 times the width. find the length and width

The dimensions of the yard are W=20ft and L=40ft.

Step-by-step explanation:

Let be:

W: width of the yard.

L:length.

Now, we can write the equation of that relates length and width:

(Equation #1)

The area of the yard can be expressed as (using equation #1 into #2):

(Equation #2)

Since the Area of the yard is , then equation #2 turns into:

Now, we rearrange this equation:  

We can divide the equation by 5 :

We need to find the solution for this quadratic. Let's find the factors of 160 that multiplied yields -160 and added yields -12. Let's choose -20 and 8, since and . The equation factorised looks like this:

Therefore the possible solutions are W=20 and W=-8. We discard W=-8 since width must be a positive number. To find the length, we substitute the value of W in equation #1:

Therefore, the dimensions of the yard are W=20ft and L=40ft.

found it xd it ok yt

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
