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:
\(x(4x)=144\)
\(4x^{2} =144\)
\(x^{2} =36\\\)
\(x=6\\\)
Then you can use this to find the width and the length.
