\n" ); document.write( "The length of a rectangle is 2 cm more than twice its width.
\n" ); document.write( "If the perimeter of the rectangle is 52 cm, find the dimensions of the rectangle.\r
\n" ); document.write( "\n" ); document.write( "What is asked in the problem?
\n" ); document.write( " find the dimensions of the rectangle.\r
\n" ); document.write( "\n" ); document.write( "Given:
\n" ); document.write( " The length of a rectangle is 2cm more than twice its width
\n" ); document.write( " The perimeter of the rectangle is 52cm\r
\n" ); document.write( "\n" ); document.write( "Representation:
\n" ); document.write( " Let x = the width of the rectangle
\n" ); document.write( " 2x+2 = the length of the rectangle\r
\n" ); document.write( "\n" ); document.write( "Equation
\n" ); document.write( " 2l + 2w = P
\n" ); document.write( " 2(2x+2) + 2x = 52 Multiply (Distributive Property)
\n" ); document.write( " 4x + 4 + 2x = 52 Combine like terms
\n" ); document.write( " 6x + 4 = 52
\n" ); document.write( " 6x + 4 - 4 = 52 - 4 subtract 4 both sides
\n" ); document.write( " 6x = 48 divide both sides by 6
\n" ); document.write( " x = 8 cm -----> Width\r
\n" ); document.write( "\n" ); document.write( " length = 2x + 2
\n" ); document.write( " = 2(8) + 2
\n" ); document.write( " = 16 + 2
\n" ); document.write( " = 18 cm ----- length\r
\n" ); document.write( "\n" ); document.write( "Checking\r
\n" ); document.write( "\n" ); document.write( " 2L + 2W = P
\n" ); document.write( " 2(18) + 2(8) = 52
\n" ); document.write( " 36 + 16 = 52
\n" ); document.write( " 52 = 52\r
