A rectangular flower bed with width 12 feet and length 15 feet is going to have a walkway of uniform width on all sides. If the area of the walkway is 90 square feet, how wide is the walkwayAnswer by mananth(13127)   (Show Source): You can put this solution on YOUR website!A rectangular flower bed with width 12 feet and length 15 feet is going to have a walkway of uniform width on all sides. If the area of the walkway is 90 square feet, how wide is the walkway let the width of the walkway be x feet flowerbed length = 15 feet flower bed width = 12 feet length of plot with walkway = 15+2x width of plot with walkway = 12+2x Area of plot - area of flower bed = area of walkaway (12+2x)(15+2x)- 12*15 = 90 180+24x+30x+4x^2-180=90 4x^2+54x-90=0 4x^2+60x-6x+90=0 4x(x+15)-6(x+15)=0 (x+15)(4x-6)=0 x=-15 OR x=3/2 So the width of the walkaway = 1.5 feet Ananth
