Abcd is a rectangle. find the length of each diagonal. ac = 2(5a+1) bd = 2(a+1)

For this case we have the following diagonals.

Since it is a rectangle, then the length of the diagonals is the same.

We have then:

AC = BD

Substituting values we have:

Rewriting:

Clearing the value of a we have:

Substituted the value of a in any of the equations we have:

The length of each diagonal is:

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

the final price would be 29.6925
