Plz i need quick ! the perimeter of a rectangular wooden deck is 90 feet. the deck's lenght, l, is 5 feet less than 4 times its width, w. which system of linrar equations can be used to determine the dimensions, in feet, of the wooden deck?

First thing you should do is simplify the question they are asking for the parameter and you know the parameter is two times the length plus two times the width.

we know the only thing that is changing in this equation is the length and the perimeter
