These 2 sides 2 ft. & 1.5 ft. along with the diagonal of the rectangle form a right triangle.
\n" ); document.write( "Thus we have the formula for the 3 sides of a right triangle:
\n" ); document.write( "a^2+b^2=c^2
\n" ); document.write( "2^2+1.5^2=c^2
\n" ); document.write( "4+2.25=c^2
\n" ); document.write( "c^2=6.25
\n" ); document.write( "c=sqrt6.25
\n" ); document.write( "c=2.5 ft. ans. for the length of the long side (hypotenuse) of the triangle and the diagonal of the rectangle.
\n" ); document.write( "Proof:
\n" ); document.write( "2^2+1.5^2=2.5^2
\n" ); document.write( "4+2.25=6.25
\n" ); document.write( "6.25=6.25
\n" ); document.write( "
\n" );
