Answer 1

$\sf </p><p>Length \: of \: sides \: of \: triangle \: are \\\\\sf \: (x-2)\: and \: (x+2) \: cm \\\\\sf </p><p>Now, \: by \: Pythagoras \: theorem, we \: have \\\\\sf </p><p>=H^2= (x-2)^2+(x+2)^2 \\\\\sf </p><p>=H^2=x^2+4-4x+x^2+4+4x \\\\\sf </p><p>=H^2=2x^2+8 \\\\\sf </p><p>H^2=2(x^2+4) \\\\\sf </p><p>H= \sqrt{2(x^2+4)}$
