document.write( "Question 349989: A landscaper, who just completed a rectangular flower garden measuring 6 feet by 10 feet, orders 1 cubic yard of premixed cement, all of which is to be used to create a border of uniform width around the garden. If the border is to have a depth of 3 inches, how wide will the border be? \n" ); document.write( "

garden = 6ft by 10ft. Area of garden = 60 sq. ft.
\n" ); document.write( "1 cu. yard = 3*3*3 = 27 cu.ft
\n" ); document.write( "..
\n" ); document.write( "The volume of concrete border = 27cu.ft.
\n" ); document.write( "the thickness = 3 inches. = 3/12 ft = 1/4 ft.
\n" ); document.write( "...
\n" ); document.write( "volume of concrete = L*W*H
\n" ); document.write( "L*W= volume / height
\n" ); document.write( "volume = 27cu.ft
\n" ); document.write( "height or thickness = 3in.
\n" ); document.write( "Area of the border = 27/(1/4 )
\n" ); document.write( "L*W= 27*4/1 = 108 sq. inches.
\n" ); document.write( "..
\n" ); document.write( "area of garden + area of border = 60+108 = 168 sq.ft
\n" ); document.write( "let width of border be x feet. increase in length & width =2x
\n" ); document.write( "(6+2x)(10+2x)= 168 sq. ft
\n" ); document.write( "60+12x+20x+4x^2=168
\n" ); document.write( "4x^2+32x+60-168 =0
\n" ); document.write( "4x^2+32x-108=0
\n" ); document.write( "/4
\n" ); document.write( "x^2+8x-27 =0
\n" ); document.write( "solve by quadratic formula you get x = 2.56 feet.
\n" ); document.write( "The width will be 2.56 feet\r
