A picture is 5cm longer than it is wide. It is in a frame that has a width of 4cm. The area of the frame alone is 344cm squared. Find the dimensions of the picture. List steps
\n" ); document.write( "--------------------------
\n" ); document.write( "Draw the picture of a rectangle inside a rectangle.
\n" ); document.write( "Let the width of the picture be \"x\".
\n" ); document.write( "Then length of the picture is \"x+5\".
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Area of the picture is x(x+5) = x^2 + 5x
\n" ); document.write( "------------------------------------
\n" ); document.write( "Outside rectangle has a width of x+8
\n" ); document.write( "Outside rectangle has a length of x+5+8 = x+13
\n" ); document.write( "----------------------------------------------------
\n" ); document.write( "Total Area of the outside rectangle including the picture
\n" ); document.write( "is (x+8)(x+13) = x^2 + 21x + 104
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "Total area - picture area = fram area = 344
\n" ); document.write( "x^2 + 21x + 104 -(x^2+5x) = 344
\n" ); document.write( "16x + 104 = 344
\n" ); document.write( "16x = 240
\n" ); document.write( "x = 15
\n" ); document.write( "-------------------
\n" ); document.write( "Width of the picture = x = 15 cm
\n" ); document.write( "Length of the picture is \"x+5\" = 20 cm
\n" ); document.write( "========================================
