Is the area of the rectangle more than the area of the square?
(1) The side of the square is half the sum of the length and the breadth of the rectangle.
(2) The length and breadth of the rectangle are 15 cm and 10 cm respectively.

IMO A..
a = (l+b)/2
Squaring both sides..
a^2 = ( l^2 + b^2 )/2 + lb
So area of square = some positive number + area of rectangle
So area of square > area of rectangle
P.s. : there was a mistake in my solution. . The denominator would be 4 not 2.

Say the length of a side of the square is x and the lengths of the length and breadth of the rectangle are a and b. So, the question is whether ab > x^2.
(1) The side of the square is half the sum of the length and the breadth of the rectangle --> x = (a+b)/2. The question becomes whether ab > ((a+b)/2)^2 --> is 4ab > a^2 + 2ab + b^2 --> is 0 > (a - b)^2. Since the square of a number cannot be negative, then the answer to this question is NO. Sufficient.
(2) The length and breadth of the rectangle are 15 cm and 10 cm respectively. We don't know x. Not sufficient.
Answer: A.
Hope it's clear.
