As per the qs \"Two legs of a right triangle are the same.\" which means it is an isoceles rt angled triangle.\r
\n" ); document.write( "\n" ); document.write( "Let the sides be x
\n" ); document.write( "Hypotenuse= 6 mts\r
\n" ); document.write( "\n" ); document.write( "therefore we can write\r
\n" ); document.write( "\n" ); document.write( "x^2 + x^2 = 6^2
\n" ); document.write( "or, 2x^2=36
\n" ); document.write( "or, x^2 = 18 (Divided either sides by 2)
\n" ); document.write( "or, x = +-sqrt(18)\r
\n" ); document.write( "\n" ); document.write( "As x can only be positive we will take the positive value which is\r
\n" ); document.write( "\n" ); document.write( " $\"sqrt%2818%29=+3sqrt%282%29\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
