You can do this !

Since d=3, take your pencil and write the fraction again,
except wherever 'd' appears, write a '3' there instead.

Then you'll have a fraction with nothing but numbers in it, and
you can easily simplify and find the value of the fraction.

I did it in my head as I was looking over the picture, and
I found that the value of the fraction is between 5 and 10.
I don't want to just hand you the answer, because I know
that you can do it.

Need help with this diagram
Anit [1.1K]

The width of the square garden is 4 feet

<h3>How to determine the width of the garden?</h3>

The area of the garden is given as:

x^2 + 20x + 75 = 171

Subtract 171 from both sides

x^2 + 20x - 96 = 0

Expand

x^2 + 24x - 4x - 96 = 0

Factorize

x(x + 24) - 4(x + 24) = 0

Factor out x + 24

(x - 4)(x + 24) = 0

Solve for x

x = 4 or x =-24

The width of the garden cannot be negative.

So, we have:

x = 4

Hence, the width of the garden is 4 feet
