Answer:
[tex]18=\frac{W}{2}-4[/tex]
18 equals StartFraction w Over 2 EndFraction minus 4
Step-by-step explanation:
Let
L ----> the length of rectangle in units
W ---> the width of rectangle in units
we know that
[tex]L=\frac{W}{2}-4[/tex] ----> equation A
[tex]L=18\ units[/tex] ----> equation B
substitute equation B in equation A
[tex]18=\frac{W}{2}-4[/tex]
so
18 equals StartFraction w Over 2 EndFraction minus 4
Solve for W
Multiply by 2 both sides
[tex]36=W-8[/tex]
Adds 8 both sides
[tex]W=44\ units[/tex]
