The Perimeter Of A Parallelogram Is 72 Meters. The Width Of The Parallelogram Is 4 Meters Less Than It’s Length. Find The Length

saul85 [17]

The width would be x-4 and

Length would be x

Add all of the sides together

(x-4)+(x-4) + x + x =72,

Which would come out

4x-8=72

Subtract 8 fro, 72 and you get 64

Then divided 64 by 4

So. Width is 16 and length is 20 . given (x-4)

Answer:

Note that the tangents to the circles at A and B intersect at a point Z on XY by radical center. Then, since∠ZAB=∠ZQA and ∠ZBA=∠ZQB. ∠AZB+∠AQB=∠AZB+∠ZAB+∠ZBA=180°. ∴ZAQB is cyclic.But if O is the center of w, clearly ZAOB is cyclic with diameter ZO, so ∠ZQO is 90° ⇒Q is the mid-point of XY.Then, by Power of a Point, PY· PX = PA · PB = 15 and it is given that PY+PX = 11. Thus,PX=(11± $\sqrt{61}$ )/2. So, PQ= $\frac{\sqrt{61} }{2}$ , PQ²= $\frac{61}{4}$ . Thus, the answer is 61+4=65.
