You can put this solution on YOUR website!
a and b are the sides of rectangular, we know that one side is 2 meters longer than the other then b= a+2 and we know that diagonalis d =10m . Now you can use Pythagorean theorem to find a
\n" ); document.write( " \"a%5E2+%2B+%28a%2B2%29%5E2=10%5E2\"
\n" ); document.write( "\"a%5E2%2B+a%5E2%2B2%2A2%2Aa%2B2%5E2=100\"
\n" ); document.write( "\"2%2Aa%5E2%2B4%2Aa-96=0\"
\n" ); document.write( "using formula for quadratic equation find a \r
\n" ); document.write( "\n" ); document.write( "\"Aa%5E2%2BB%2Aa%2BC=0\"
\n" ); document.write( "where: A=2, B=4, C=-96\r
\n" ); document.write( "\n" ); document.write( "\"B%5E2-4%2AA%2AC=+16-4%2A2%2A%28-96%29=784\"\r
\n" ); document.write( "\n" ); document.write( "equation has 2 solutions:\r
\n" ); document.write( "\n" ); document.write( "\"a1=%28-B-sqrt%28B%5E2-4%2AA%2AC%29%29%2F%282%2AA%29\"
\n" ); document.write( "\"a1=%28-4-sqrt%28784%29%29%2F%282%2A2%29\"
\n" ); document.write( "a1=-8 it can not be solution because lenght can not have negative value\r
\n" ); document.write( "\n" ); document.write( "\"a2=%28-B%2Bsqrt%28B%5E2-4%2AA%2AC%29%29%2F%282%2AA%29\"
\n" ); document.write( "\"a2=%28-4%2Bsqrt%28784%29%29%2F%282%2A2%29\"
\n" ); document.write( "a2=6
\n" ); document.write( "
\n" ); document.write( "If a = 6 meters and b = a+2 , then b= 8meters\r
\n" ); document.write( "\n" ); document.write( "Answer: the sides of rectangular stage are 6 & 8 meters long\r
