Width of a rectangle is 5cm shorter than the length. Perimeter is is 290 cm, Find the sides.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. Let L be the length of the rectangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2. Let L-5 be the width of the rectangle\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3. Perimeter P means adding all four sides of the rectangle. \"P=L%2BL%2BL-5%2BL-5=4L-10=290\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Solving yields the following steps\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"P=4L-10=290\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Add 10 to both sides of the equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4L-10%2B10=290%2B10\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4L=300\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide 4 to both sides of the equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4L%2F4=300%2F4\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"L=75\" AND \"L-5=70\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check \"Perimeter=P=2%2875%2B70%29=290\"...which is a true statement.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 5. ANSWER: The sides of the rectangle are 75 cm and 70 cm.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I hope the above steps were helpful.\r
