It is a right triangle w/ a=1, b=.5, to find c:\r
\n" ); document.write( "\n" ); document.write( "c^2 = a^2 + b^2 take the square root of both sides\r
\n" ); document.write( "\n" ); document.write( "c= $\"sqrt%281%5E2+%2B+.5%5E2%29\"$ = $\"sqrt%281.25%29\"$ = 1.118\r
\n" ); document.write( "\n" ); document.write( "To find how far she walked, just find the perimeter of the triangle \r
\n" ); document.write( "\n" ); document.write( "P = a + b + c = 1 + .5 + 1.118 = 2.618 miles, roughly\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
