The length of a square is increased by 15% and breadth decreased by 15...
Explanation:
Let the length of the square be L and breadth be B.
The initial area of the square is L x B.

After increasing the length by 15%, the new length becomes 1.15L.
After decreasing the breadth by 15%, the new breadth becomes 0.85B.

The new area of the rectangle is (1.15L) x (0.85B) = 0.9775(L x B).

The percentage decrease in area is calculated as:
= (Initial area - Final area) / Initial area x 100%
= ((L x B) - 0.9775(L x B)) / (L x B) x 100%
= 0.0225 x 100%
= 2.25%

Therefore, the area of the rectangle decreases by 2.25%. Hence option B is the correct answer.
