This is a perimeter of a rectangle problem. Perimeter (P) of a rectangle is the sum of all sides
\n" ); document.write( "P = 2 x length + 2 x width.\r
\n" ); document.write( "\n" ); document.write( "In this problem the Perimeter (P) = The amount needed for the area Tom wants to enclose
\n" ); document.write( "Question: How many yards are leftover?
\n" ); document.write( "Leftover = Amount bought – amount needed
\n" ); document.write( "
\n" ); document.write( "Given information:
\n" ); document.write( "Rectangle = 30 yards long by 20 yards wide
\n" ); document.write( "Amount Bought = 125 yards\r
\n" ); document.write( "\n" ); document.write( "Step 1: Find the Perimeter(P)of rectangle 30 yards long and 20 yards wide.
\n" ); document.write( " P = 2 x length + 2 x width.
\n" ); document.write( " P = (2 x 30) + (2 x 20)
\n" ); document.write( " P = 60 + 40
\n" ); document.write( " P = 100\r
\n" ); document.write( "\n" ); document.write( "Step 2: Find the yards leftover.
\n" ); document.write( " Leftover = Bought – Needed
\n" ); document.write( " Leftover = 125 - Perimeter
\n" ); document.write( " Leftover = 125 - 100
\n" ); document.write( " Leftover = 25\r
\n" ); document.write( "\n" ); document.write( "Answer: 25 yards is leftover
\n" ); document.write( " \n" ); document.write( "
\n" );
