Answer 4

Is it A?

Answer 5

512/4=128

Answer 6

nah nah
see it says four times
so s = q/4
and r = p/4

Answer 7

Ok.. Can you use actual numbers?

Answer 8

hmmm wht do u mean???

Answer 9

Can you give me an explanation with the answer?

Answer 10

@rishavraj

Answer 11

see its given p = 4r ...so r = p/4
and q = 4s so s = q/4
area of rect. A = 512
so , p*q = 512

Answer 12

now for rect. B
area = r*s
so its (p/4)*(q/4)

Answer 13

so its area is \[\frac{ pq }{ 16 }\]
and u hav pq = 512
so just plug tht
