Answer:
The width is 6 and the length is 24.
Step-by-step explanation:
You need to create an equation using the area, because we know that the width is 1/4 of the length we can use x for both values:
[tex]x(4x)=144[/tex]
[tex]4x^{2} =144[/tex]
[tex]x^{2} =36\\[/tex]
[tex]x=6\\[/tex]
Then you can use this to find the width and the length.
