Respuesta :

L= 3x

Area = l x w

Since you don’t know the width represent it by x

3x(x) = 192

X= -8 or x= 8
Your answer can’t be negative number

So the length is 3(8) = 24 yards

Hope this helpes!

Please mark me as brainliest if you can, I really appreciate it!

It is 24 yards long.

Let the width = x

Given that the rectangular field is 3 times as long as it is wide.

So, the length = 3x.

So area = Length * width = [tex](3x)*(x) = 3x^2[/tex].

Given:  it has an area of 192 square yards.

So,

[tex]3x^2=192\\x^2=64\\x=\sqrt{64}\\x=8[/tex]

So length = 3x = 3(8) = 24.
