He dug the garden bed long and narrow to measure 3 feet by 10 feet, so that he could tend more easily to his plants. He would like to build a brick patio of equal width surrounding the garden. The area that the bricks cover is 100 square feet. How wide should the patio measure? \n" ); document.write( "

width of garden = 3
\n" ); document.write( "length = 10
\n" ); document.write( "area = 30 ft^2
\n" ); document.write( "..
\n" ); document.write( "let the patio width be p
\n" ); document.write( "total width will be 3+2p
\n" ); document.write( "total length = 10+2p
\n" ); document.write( "..
\n" ); document.write( "Area of patio = 100 ft^2
\n" ); document.write( "...
\n" ); document.write( "Total area = (10+2p)(3+2p)
\n" ); document.write( "(10+2p)(3+2p)- 30 = 100
\n" ); document.write( "30+26p+4p^2-30=100
\n" ); document.write( "4p^2+26p-100=0
\n" ); document.write( "/2
\n" ); document.write( "2p^2+13p-50=0use quadratic formula
\n" ); document.write( "discriminant = 569
