To find the perimeter of a square, take 4 times the length of one side:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4(5x + 2) = 48 {four times one side equals the possible perimeter}
\n" ); document.write( "20x + 8 = 48 {used distributive property}
\n" ); document.write( "20x = 40 {subtracted 8 from each side}
\n" ); document.write( "x = 2 {divided each side by 0}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To find the area of a square, just square one side:
\n" ); document.write( "5x + 2 is one side
\n" ); document.write( "= 5(2) + 2 {substituted 2 for x}
\n" ); document.write( "= 10 + 2 {multiplied}
\n" ); document.write( "= 12 {added}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "therefore, one side is 12
\n" ); document.write( "the area is 12², which is 144 square units
\n" ); document.write( "
