Given: A= 14 ft² and l= 2w-3 formula for area of a rectangle is A=lw substitute for what you know and simplify: 14=(2w-3)w -> w= either -2 or 7/2 but because a width value can not be negative you can eliminate the -2 value. w=7/2 subsitute width into equation for length and solve l=2w-3= 2(7/2)-3= 4 width: 3.5 ft length: 4 ft
