In a quadrilateral PQRS,PQRS,PQRS, if PQRS,S=2Q,PS=qPQRS,S=2Q,PS=qPQRS,S=2Q,PS=q and RS=p.RS=p.RS=p. Find the length of the side PQ.PQ.PQ.


Answer:

p+qp+qp+q

Step by Step Explanation:
  1. Let us first draw the quadrilateral PQRSPQRSPQRS.
      P Q R S 2x x E
    Let Q=xQ=xQ=x
    So, S=2xS=2xS=2x
    Let us join RRR to a point EEE on the side PQPQPQ such that PERSPERSPERS is a parallelogram.
  2. We know that opposite sides of a parallelogram are equal.
    So, PSR=PER=2x(i)PSR=PER=2x(i)PSR=PER=2x(i)

  6. We are given that RS=pRS=p and PS=q.PS=q.
    As, opposite sides of a parallelogram are equal,
    RS=PE=pRS=PE=p
    and PS=ER=qPS=ER=q
    EQ=q[From (ii)]EQ=q[From (ii)]
  7. We can see that PQ=PE+EQ=p+qPQ=PE+EQ=p+q
  8. Thus, PQ=p+qPQ=p+q
