If the focus<span> of a </span>parabola<span> is and the </span>directrix<span> is , find the</span>equation<span> of the </span>parabola. Let ( x 0 , y 0 ) be any point on theparabola. Find the distance between ( x 0 , y 0 ) and the focus. Then find the distance between ( x 0 , y 0 ) and directrix<span>.</span>
4cm•2=8cm which is the length of the red paper so therefore Red paper= 4cmx8cm. Then your going to take 3cm-4cm= 1cm Next your going to solve for 7cm-8cm=1cm Which leaves you with an answer of 1cmx1cm more of visible red paper.
