The area of a square is equal to one of its sides squared
\n" ); document.write( "OR
\n" ); document.write( "\"A=S%5E2\"
\n" ); document.write( "This problem states that if the sides of a square are increased by 5 the area becomes 289
\n" ); document.write( "so lets plug that information into the formula for area of a square
\n" ); document.write( "\"A=S%5E2\"
\n" ); document.write( "\"289=%28s%2B5%29%5E2\"
\n" ); document.write( "now just solve for s
\n" ); document.write( "first take the square root of both sides of the equal sign
\n" ); document.write( "\"sqrt%28289%29=sqrt%28%28s%2B5%29%5E2%29\"
\n" ); document.write( "\"17=s%2B5\"
\n" ); document.write( "\"12=s\"
\n" ); document.write( "so the sides of the original picture frame are 12 cm
\n" ); document.write( "Check answer
\n" ); document.write( "\"289=%28s%2B5%29%5E2\"
\n" ); document.write( "\"289=%2812%2B5%29%5E2\"
\n" ); document.write( "\"289=%2817%29%5E2\"
\n" ); document.write( "\"289=289\"
\n" ); document.write( "done!
\n" ); document.write( "
\n" );
