C The total length of the large rectangle is 30 meters more than the total length of the small rectangle.
D The total length of the large rectangle is equal to 160 meters and the total length of the small rectangle is equal to 100 meters.


option A and C are both correct. If D is the correct option then instead of length you should make it more specific to say length of the boundary. A rectangle by definition has 2 sides length and breadth

The correct answer is D because the total length of the large rectangle is 160 meters and the total length of the small rectangle is 100 meters

Ans 11:

The word should be PERIMETER as the word TOTAL LENGTH [mentioned] can mean the sum of the 2 sides of the rectangle and can not be understood very well.So, according to me the answer can be both A as well as C.
