Given: A= 52ft² and l= 2w-5 know that formula for A= lw, substitute for what you know and solve for w 52=(2w-5)w -> w= -4, w=6.5 but because a width measurement can not be negative, you can eliminate w=-4. so the width is equal to 6.5ft now input that in the equation for length and solve for l: l=2w-5=2(6.5)-5=8 so the length is 8 ft
