Answer:

Step-by-step explanation:

we're given that

[tex]W = 2X - 3\\P = 43\\[/tex]

the perimeter can be defined as

[tex]P = 2X + 2W \\so\\43 = 2X + 2(2X - 3)\\43 = 2X + 4X - 6\\6X = 49\\X = \frac{49}{6}\\ W = 2X - 3\\W = 2(49/6) - 3\\W = 49/3 - 9/3 = \frac{40}{3}[/tex]

The rectangle is

[tex]\frac{49}{6} by \frac{40}{3}[/tex] feet
