Question

If P(2, 4), Q(0, 3), R (3, 6) and S(a, b) are vertices of a parallelogram then the value of a + b is ..........

Answer 1

Answer:

apply mid point theorem

on line pr.

o(5/2,5)=o(a/2,b+3/2)

a=5. and b=7/2

a+b=17/2

Answer 2

Answer:

Applying mid point formula

(0+a/2 ,3+b/2)=(2+3/2 ,4+6/2)

a/2=5/2 ;3+b/2=10/2

a=5 ; b=7

Now a+b

5+7=12
