III. The length is twice the width.

A. I and II only
B. II and III only
C. I and III only
D. I, II, and III

Answer 1

definately C,
as when calculated :
let length be x and breadth be y;
then we take two conditions that the are a is 98 while the perimeter is 42,
so x*y=98
and 2(x+y)=42
the answer comes length is 14 while bredth is 7 sou get first and third are true

Answer 2

C

7 x 14 = 98

7+7+14+14= 42

Answer 3

C

2 is definitely not true
