|Perimeter of a rectangle is 2(L+B),as per 1st and 2nd statement
Perimeter is 60cm and Breath is 12 cm then
now we can find the area of rectangle by using formula
that is 12x18=216

|In General perimeter of a rectangle is ]
we cant get any l and b values by usign 1 an 2 statements
we can get answer by taking 2 and either 1 or 3

|If first and second is find then we also find area of wall
because we know 2*(l+b)then l+b is given.

So perimeter=2(l+b)=2*30=60 i.e. given so only 1 and 3 rd is correct

|This answer is wrong in place of finding what is redundant you have you have answered what is/are necessary!By the given logic II is essential in both combinations- I+II & II+III.It is not redundant.|

|This answer is wrong because we found the value with combination of I+II & II+III. It is not redundant.|

|The answer to the question can be found using any 2 of the three. Then how can the any 1 of the options be chosen as redundant ?|
|Karan said: (Sep 1, 2016)|
|The question asked here is "Which statement/s are redundant. So either statement I or III can be redundant (for which there is no option). The most appropriate answer would be "[A] I only".
However, the answer given here is telling us which statement is necessary!

|Can anybody explain, how 2 is redundant? I found it completely useful.|
