Answer:
21.75
Step-by-step explanation:
Plugging in the variables, you'd get 24 - (20-4) over (4 + 4). Add the contents of the parenthesis and you'd get 24 - (18)/(8). You'd divide, and get 24- 2.25, or 21.75.
If you aren't supposed to simplify on this assignment, it would probably be 24 - 18/8, or if you use fractions 21 and 3/4.
We are told that l is the length of the rectangle. We are told that the widht is 4 less than half the lenght. So, first, we calculate the half of l, which would be

the part that says "4 less than" means that we should subtract 4 from the half of length. So we get

now, this expression should be equal to the width , that we'll note as w. So we end up with the equation
